Okolie, C.C. "Legal Requirements for the World's Protection of Outer Space and Earth Environments Within the Perspective of
Directed Energy Weapons." In: Colloquium on the Law of Outer Space, 25th, Paris, France, September 27," October 2, 1982. New York, NY: American Institute of Aeronautics and Astronautics, 1983, p.
25-35. Abstract:Space law considerations of directed energy weapons are discussed. The possibility of such weapons being deployed is examined
in terms of international treaties and the capabilities of the superpowers and their ongoing programs in the area. A new international
treaty to be submitted to the United Nations is proposed for the protection of the earth and outer space environments and
for banning the development and testing of directed energy weapons in outer space. Loopholes in existing treaties are identified.
The role of the third world in promoting reciprocity between the U.S. and the U.S.S.R. is addressed. A U.S. case law which
may be applicable to the issue is discussed. REPORT NUMBER: IAF Paper 82-IISL-08

on the ESS-7 Photometers Project. Some hardware was procured/fabricated for the ESS-7 Photometer task, however, most of the
work consisted of design and engineering support resulting in drawings and specifications which were prepared by MEE-12 personnel.
There were no technical papers or patents generated by Optomec personnel as a result of this work, and all work defined in
the contract was completed. REPORT NUMBER: LA-SUB-93-156 ACCESSION NUMBER: DE-96-000174
Orr, J.S., H. Gordon and H. Orr. "Vanadium Dioxide Protective Devices." Final technical report. Dunfermline (Scotland): OCLI/Optical
Coatings Ltd., June 1989. 33p. Abstract:This development contract has been carried out in order to answer the increasing requirement for protection of sensitive infrared
detectors from pulsed laser radiation in the military environment. It has been the concern of this project to develop a protective
device for use in the 8-12 micron wavelength region. The approach in this case has been to exploit the well established optical
properties of vanadium dioxide thin films in the infrared. This report presents in detail the equipment and methods used to
obtain thin films of vanadium dioxide for incorporation in protective devices. A significant development effort has been directed
at the inclusion of switching films in antireflection coatings for the 8-12 micron band. The subject of this contract was
the development of vanadium dioxide optical switches. The aim was to further develop the reactive sputtering process for deposition
of vanadium dioxide. Vanadium dioxide can now be deposited on germanium as well as silicon and has been fully characterized.
The process stability, repeatability and the quality of the vanadium dioxide has been significantly improved. In particular
the optical scatter has been reduced and the dynamic range has been increased. Devices incorporating vanadium dioxide have
been manufactured to the required specification and indications are that the devices should fulfill their intended purpose. ACCESSION NUMBER: AD-A212 018

cross section, its yield, its wavelength dependence, and its dependence on surface conditions for two important metal- alkyl
precursors. Second, we have successfully initiated a substantial new program in UV-laser photoemission for surface probing.
This work has included establishing a new, tunable two-photon photoemission apparatus including UHV chamber with an electron
detection system, demonstration of a new technique to probe buried interfaces, the use of high-resolution, two-photon spectroscopy
to probe surface-condition-dependent changes via image states, and the observation of space-charge-limited effects on surface
photoionization spectroscopy. ACCESSION NUMBER: AD-A253 510
O'Shea, P.G. "Linear Accelerator in the Space: The Beam Experiment Aboard Rocket." Los Alamos National Laboratory, NM. 1990.
14p. In: Linear Accelerator Conference, Albuquerque, NM, 9-14 September 1990. Abstract:On July 13, 1989 the BEAM experiment Aboard Rocket (BEAR) linear accelerator was successfully launched and operated in space.
The flight demonstrated that a neutral hydrogen beam could be successfully propagated in an exoatmospheric environment. The
accelerator, which was the result of an extensive collaboration between Los Alamos National Laboratory and industrial partners,
was designed to produce a 10 mA (equivalent), 1 MeV neutral hydrogen beam in 50 (mu)s pulses at 5 Hz. The major components
were a 30 keV H(sup (minus)) injector a 1 MeV radio frequency quadrupole, two 425 Mhz RF amplifiers, a gas cell neutralizer,
beam optics, vacuum system and controls. The design was strongly constrained by the need for a lightweight rugged system that
would survive the rigors of launch and operate autonomously. Following the flight the accelerator was recovered and operated
again on the laboratory. REPORT NUMBER: LA-UR-90-3441, CONF-90091234-6 ACCESSION NUMBER: DE-91-002347

"Overview of Defense Applications of ICF (Inertial Confinement Fusion)." Livermore, CA: Lawrence Livermore National Laboratory,
15 August 1989. 9p. Abstract:The objective of the Inertial Confinement Fusion (ICF) Program is to demonstrate a significant fusion capability in the laboratory.
The applications of ICF are broad and numerous, ranging from basic and applied science to weapons physics and weapons effects
to energy production and eventually space power and propulsion. This paper is limited to a brief summary of the applications
of ICF to defense programs, and in particular, the nuclear weapons R & D and technology base. While relevant weapons physics
experiments are currently conducted using the Nova laser, the ultimate contribution of ICF in this area will be a Laboratory
Microfusion Facility (LMF) in which fusion yields of 100 to 1000 MJ, provided in a single experimental shot, can be used to
attain the near-term applications. REPORT NUMBER: UCID-21837 ACCESSION NUMBER: DE-90-005745

Proceedings of the Symposium on Lasers and Particle Beams for Fusion and Strategic Defense, Rochester, NY, 18-19 April 1985
p. 57-72. Fusion Power Associates; Gaithersburg, MD, 1985. Abstract:Pulsed power technology has been developed over many years for nuclear weapon effects simulation, inertial fusion, and directed
energy. Every four years there is a factor of ten increase in power available, and one is now near the 100 TW, couple of million
joule mark. A million joules (MJ) is the energy required to kill a booster and 100 TW is sufficient for studying physics relevant
to inertial confinement fusion (ICF) or the Strategic Defense Initiative (SDI). The applications of this technology are many.
Pulsed power should be viewed as a basic technology for making electron beams, X-rays, and ion beams. Applications include
ICF, plasmoid directed energy weapons, X-ray lasers, electron beams as directed energy weapons, and microwave weapons.

Penatzer, Jeffery L. "Enhancement of Multiple Target Track Simulation." Final technical report. May 1989-April 1990. Rome,
NY: Analytical Systems Engineering Corp., August 1992. 37p. Abstract:The Enhancement of Multiple Target Track Simulation task had as its primary objective the development of an integrated simulation
of Strategic Defense Initiative (SDI) Acquisition, Tracking, Pointing, and Fire Control (ATP-FC) functions from previously
developed simulations of a subset of the individual functions which would be required for a complete end-to-end simulation
of a space-based Directed Energy Weapon (DEW) platform. The functions integrated were the Target Detection, Multiple Target
Tracking (MTT), and Target Sequencing functions. Additionally, the Plume-to-Hardbody Handover function was partially integrated.
The task consisted of the following subtasks: (1) Incorporation of previously developed target sequencing algorithms (Nearest
Neighbor and Farthest Insertion) into a previously existing MTT simulation, (2) Investigation and incorporation of an improved
target detection algorithm to replace the target detection algorithm that was included with the original previously existing
MTT simulation, and (3) Incorporation of previously developed Plume-to-Hardbody handover algorithms into the combined MTT
and target sequencing simulation. This report summarizes the work performed in accomplishing these three subtasks. ACCESSION NUMBER: AD-A257 224
Penrod, Shawn L. "An Endo-Atmospheric Hypervelocity Intercept System." Final report. 1977-1988. Annapolis, MD: Naval Academy,
10 June 1988. 117p. Abstract:This study examines the feasibility and practicality of using clouds of hypervelocity pellets to intercept and disable a generic
air target. The Directed Energy Projectile Warhead which accelerates these pellets, uses an unconventional design to attain
speeds an order of magnitude above those of conventional high explosive warheads. The DEPW is fitted to a conventional intercept
missile to put the target in effective range of the warhead, which then detonates, and launches the pellets very much like
a hypervelocity shotgun. An extensive three-dimensional computer simulation was developed using ACSL(Advanced Computer Simulation
Language) and FORTRAN. The program models the terminal homing phase of a missile intercept to evaluate the effectiveness of
different guidance laws used to align the warhead with the projected intercept point. After a favorable geometry has been
achieved, the warhead is detonated and the lethality of impact between the target and hypervelocity pellet cloud is evaluated.
Overall effectiveness of this system is shown to depend on the pointing accuracy of the warhead and the firing range. No insurmountable
obstacles are foreseen in developing a suitable guidance and aiming algorithm. A valuable tool to evaluate design options
has also been developed. REPORT NUMBER: USNA-TSPR-153 ACCESSION NUMBER: AD-A200 403

Weapon Detonation." Oak Ridge National Laboratory, TN. 1994. 9p. In: International Conference on Radiation Shielding (8th),
Arlington, TX, 24-27 April 1994. Abstract:Rapidly changing world events, the increased number of nations with inter-continental ballistic missile capability, and the
proliferation of nuclear weapon ?echnology will increase the number of nuclear threats facing the world today. Monitoring
these nation's activities and providing an early warning and/or intercept system via reconnaissance and surveillance satellites
and space based weapon platforms is a viable deterrent against a surprise nuclear attack. However, the deployment of satellite
and weapon platform assets in space will subject the sensitive electronic equipment to a variety of natural and man-made radiation
environments. These include Van Allen Belt protons and electrons; galactic and solar flare protons; and, neutrons, gamma rays,
and X-rays from intentionally detonated fission and fusion weapons. In this paper, the MASH vl.0 code system is used to estimate
the dose to the critical electronics components of an idealized space based weapon platform from neutron and gamma-ray radiation
emitted from a thermonuclear weapon detonation in space. Fluence and dose assessments were performed for the platform fully
loaded, and in several stages representing limited engagement scenarios. The results indicate vulnerabilities to the Command,
Control, and Communication (C) bay instruments from radiation damage for a nuclear weapon detonation for certain source/platform
orientations. The distance at which damage occurs will depend on the weapon yield (n,(gamma)/kiloton) and size (kilotons). REPORT NUMBER: CONF-940424-16 ACCESSION NUMBER: DE-94-007229
Perram, Glen P. "Visible Chemical Lasers." In: Lasers '89; Proceedings of the International Conference, New Orleans, LA, December
3-8, 1989. McLean, VA: STS Press, 1990, p. ?? Abstract:Applications for visible chemical lasers, which show great potential as highly efficient, wavelength agile, deployable, high
brightness laser systems are discussed. These systems provide important and unique opportunities for both directed energy
weapons and diagnostic applications. Issues discussed in this paper include concepts, requirements and approaches to visible
chemical lasers. A survey of candidate energy transfer system is also given, with emphasis on excited NF and nitrogen driven
lasers. The long term, low level investment in this technology area during the past decade firmly establishes the opportunity
for a lasting demonstration in the near term.

1997. p. 107-111. Abstract:The development of high-power microwave (HPM) weaponry, and its proliferation into subversive organizations, offers the means
to commit the "perfect crime." HPM attacks typically leave no residual evidence and their effects can range from nuisance
to catastrophic. The paper highlights some of the unusual aspects of HPM technology and raises issues regarding security of
airliners, commercial power systems and other targets. It also discusses strategies to begin mitigating the risks.

Incoherence at 0.53 Microseconds." Memorandum Report 6798. Washington, DC: Naval Research Laboratory, 24 May 1991. 27p. Abstract:Measurements of the omega sub 0/2 emission from Laser irradiated targets at 0.53 microns were made at three angles over a
wide range of Laser bandwidths with and without induced spatial incoherence (ISI) echelons. The 3 microns/2 emission was found
to be correlated with hard x rays but not Raman spectra suggesting that the 3 omega sub 0/2 radiation was due to two plasmon
decay. Reduction of both 3 omega sun 0/2 emission and the accompanying hard x rays by ISI required five to ten times larger
bandwidths than needed to suppress stimulated Raman scattering and stimulated Brilloin scattering. REPORT NUMBER: NRL-MR-6798 ACCESSION NUMBER: AD-A235 798
Phillips, Robert M. "Modulatable Thin Film Emission Space Gun." Final Technical Report. October 1985-June 1986. Campbell,
CA: Star Microwave, November 1987. 54p. Abstract:The objective of this research program was to determine the feasibility of using a Spindt type thin film emitter chip to produce
amperes of low voltage modulated current at tens of kilovolt beam voltage for a space application. The specific requirement
was for a pulse modulated column of electrons of 10 amperes current at 50 kilovolts voltage. A design effort determined that
a 2-inch diameter chip would be required to provide this current with conservative emission current density. A conceptual
design was developed consisting of an array of emitting regions producing beamlets which were to be accelerated through a
gridded or perforated anode at approximately 3 kilovolt voltage, followed by post-acceleration to 50 kilovolts. Feasibility
was to be demonstrated by using smaller (1/2-inch square) standard emitter chip of the type produced by SRI International
for their field emissions research program. This chip was to be tested to the same current density as would be required of
the 2-inch chip. A test electron gun employing a standard emitter chip was designed and fabricated based on the results of
a computer-derive electron optics model. Of five emitter chips started only two were successful and were delivered for use
in the test gun. One chip was lost during assembly of the test gun due to breakdown of the chip, apparently from RF leakage
while a welding process was being performed. After modifying the construction procedure, the test gun was successfully assembled.
However, during tests, this chip failed catast?ophically at one percent of the current emission which was required to demonstrate
feasibility of the approach. ACCESSION NUMBER: AD-A189 279

Consequences, EUROEM 94, Bordeaux, France, 30 May - 3 June 1994. (Gramat, France: EUROEM 1995). p3-13. vol. 1. Abstract:During the Cold War era, the nuclear weapons effects community made significant contributions to the understanding of hostile
electromagnetic effects on many types of military systems. In the United States, these contributions were made possible through
sustained government investment especially by the Department of Defense (DoD), in fundamental and applied research on electromagnetic
pulse (EMP) environments, system interactions, and protection methods. As the likelihood of large scale nuclear war has diminished,
the resources devoted to traditional EMP research has also declined. The irony in this development is that the proliferation
of weapons of mass destruction continues to rise steadily. Current circumstances provide the nuclear effects community with
a unique opportunity to apply its talents to new challenges posed by changing threats and declining resources. The electromagnetics
(EM) community must work together and be creative in developing affordable solutions to meet existing and future needs. A
systematic and integrated approach for dealing with a wide variety of nuclear and nonnuclear electromagnetic environments
holds great promise for both improved performance and cost savings. The individual and collective cooperation of members of
the international EMP and the electromagnetic effects community is essential if such an approach is to be successful.

Weapons." Livermore, CA: Lawrence Livermore National Laboratory, 22 May 1986. 8p. In: 2nd European Simulation Congress, Antwerp, Belgium, 9 September 1986. Abstract:A preliminary study was recently completed at Lawrence Livermore National Laboratory of the issues important to the integrated
modeling and simulation of future directed energy weapon (DEW) space platforms. The preliminary study comprised three parts:
(1) a preliminary survey of existing computer codes used for integrated modeling and simulation; (2) work by a multidisciplinary
team on a simple optical beam expander model to motivate cooperation in the three technical areas of space structures, optics,
and control systems; and (3) identifying needs?in integrated modeling and simulation for DEW systems. Results of this study
indicate that much of the technology for end-to-end modeling and simulation of DEW space platforms may be in hand today. However,
there may be critical needs in certain modeling and simulation areas, particularly in the package integration and computer/human
interface areas, that are beyond the current state of the art to meet required levels of performance. REPORT NUMBER: UCRL-93-765, CONF-8609113-1 ACCESSION NUMBER: DE-86-011636

Livermore National Laboratory, October 1994. 6p. In: Conference on High Power Microwaves (7th), Monterey, CA, 31 October 1994. Abstract:Performance of high power radiators of electromagnetic energy can be limited by constraints such as those due to voltage holding,
corona power loss, and antenna impedance and efficiency. The issues are addressed in such a way that general limits on the
electric field and energy at a distance is obtained as a function of wavelength, pulse duration, and size of the radiating
element. We address the relation between the frequency content of the driving pulse and the complex impedance of the antenna;
the importance of minimizing the antenna impedance and therefore limiting the antenna input voltage is clearly shown. For
example, driving the antenna at a resonance with a simple oscillating waveform is shown to allow the radiation of energy with
two to three times the efficiency of a mono-polar pulse input. With this information, the prospects for a successful system
design of a given size to deliver a specified amount of radiation to a target at a given distance can be quickly assessed. REPORT NUMBER: UCRL-JC-117133, CONF-9410341-1 ACCESSION NUMBER: DE-95-010732
Prantil, V.C. "Response of a Thin Cylindrical Shell Under Lateral Impulse Loads." Albuquerque, NM: Sandia National Labs.,
March 1988. 78p. Abstract:In support of the current directed energy weapons program investigating lethality levels of short pulse width lasers, a combined
analytical/experimental program has been underway to predict large deformation response of conceptual ballistic missile designs
to impulsive loading. Both unpressurized cylindrical shell models have been analyzed and tested. Such impulsively loaded structures
exhibit large scale plastic deformation and local dynamic pulse buckling instability which subsequently influence the loaded
surface collapse. Impulse loads were simulated using both lead spray and light initiated high explosive techniques. Finite
element calculation using a modified form of the Hughes-Liu shell element verify several characteristics of the structural
response observed in experiments. The role of the computational results in identifying lethal impulse levels and response
modes is described. In addition, the requirements for initial imperfections and fine mesh discretization for these problems
are discussed. REPOR5T NUMBER: SAND-87-8229 ACCESSION NUMBER: DE-88-008071

energy decreases substantially before reaching a critical SSE. The authors discuss the basic technical characteristics of
RFWs which are based on vircators, magnetrons, high explosive chemical energy in direct converters using magnetic field compression,
etc. In particular, the authors discuss the microwave sources. The authors then discuss the conceptual aspects of RFW application.

Summer Computer Simulation Conference, Montreal, Quebec, Canada; 27-30 July 1987. San Diego, CA: SCS, 1987. p. 931-932. Abstract:Because many of the weapons proposed for SDI cannot ever be operationally tested, simulations are playing a critical role
in the development of both kinetic energy weapon (KEW) and directed energy weapon (DEW) concepts. Moreover, even though other
SDI subsystems (such as SATKA and BM/C/sup 3/) must also be simulated, it is the weapon that lies at the heart of a credible
strategic defense. This paper gives an overview of SDI simulations that places the role of weapon simulation in proper perspective.
"Proceedings of the Eighth DOD Conference on DEW Vulnerability, Survivability, and Effects." SURVIAC (Survivability/Vulnerability
Information Analysis Center), October 1992. 2 volumes. Abstract:This conference, held in June 1992, provided a forum for discussion, interchange, and debate of accomplishments, discoveries,
and issues in the areas of vulnerability, survivability, and effects of Directed Energy Weapons (DEW) such as lasers, standards,
laser illumination tests, hazards and medical implications, capabilities, requirements, and myths. The conference was particularly
significant because of the progress made in laser technologies and in the critical military use of new materials and substances
affected by these new techno?ogies. Volume I of the proceedings details the general session and numerous presentations given
on structures (tactical and space), eye and personnel protection, space platforms, and sensors. Volume II presents poster
papers from the conference. [Proceedings of the fifth through seventh DEW conferences are also available from SURVIAC]. http://surviac.flight.wpafb.af.mil

Quick, Dennis D. "Simulations of the High Average Power Selene Free Electron Laser Prototype." Monterey, CA: Naval Postgraduate
School, June 1994. 63p. Abstract:Free electron laser (FEL) technology continues to advance, providing alternative solutions to existing and potential problems.
The capabilities of an FEL with respect to tunability, power and efficiency make it an attractive choice when moving into
new laser utilization fields. The initial design parameters, for any new system, offer a good base to begin system simulation
tests in an effort to determine the best possible design. This is a study of the Novosibirsk design which is a prototype for
the proposed SELENE FEL. The design uses a three-section, low-power optical klystron followed by a single-pass, high-power
radiator. This system is inherently sensitive to electron beam quality, but affords flexibility in achieving the final design.
The performance of the system is studied using the initial parameters. An FEL, configured as a simple, two section optical
klystron is studied to determine the basic operating characteristics of a high current FEL klystron. ACCESSION NUMBER: AD-A280 780
