Jensen, et al. "Tactics and Technology: How Do they Affect Each Other?" Washington, DC: Marine Corps, 1 April 1991, 33p.
Abstract: Research and development of new, revolutionary technologies have been extensive. The resulting military applications will drastically change the tactical nature of the battlefield. To cover every technology currently under consideration would be lengthy and beyond the scope of this paper. Rather, it is the intent of this paper to detail selected technological innovations and their tactical implications. Technological advances in space research will allow us to (1) reduce the reaction time in engaging adversary's ballistic missiles by employing boost-phase monitoring technology; (2) establish an overall command and control network for Ballistic Missile Defense (BMD) by incorporating all of our assets into an overall surveillance and tracking system; (3) engage incoming ballistic missiles in a variety of ways, using directed-energy and kinetic energy weapons, both ground and space based; and (4) engage the adversary's satellites from ground, space, and aerial-based means, hampering his ability to use satellite systems for surveillance, reconnaissance, and communication.

Bellingham, WA: Society of Photo-Optical Instrumentation Engineers, 1989, p. 573-577.
Abstract: the operation of a Dudnikov (1975)-type H(-) ion source using lanthanum hexaboride as the cathode material has been achieved and has been previously reported. The cesium-free operation achieved by using this thermionic emitter is of benefit to the overall neutral particle beam system performance. The source requirement for a neutral particle beam will require higher output from this source. The experimental apparatus is a Penning-type discharge ion source with a variable magnetic field. A brief discussion of the parametric optimization will be covered. In an effort to further increase performance of the Dudnikov source, xenon and argon have been added to the hydrogen fuel used in the source. The inert gas has been added in small amounts (0.2-2.0 percent) as the H(-) and e(-) levels were monitored. Apparatus, diagnostics and results will be discussed.

Bellingham, WA: Society of Photo-Optical Instrumentation Engineers, 1989, p. 313-341.
Abstract: The "Microwaves-To-Leo" (MTL) energy-transmission concept has been proposed to supply SDI weapons platforms with the requisite power for 'housekeeping', 'alert', and 'burst power' operational modes. An account is presently given of an MTL system's design, component integration and analysis; the parametric design of the MTL-bus subsystems, encompassing among other the rectenna and monolithic solid-oxide fuel cell, is presented and combined with a computer simulation to serve as input in the construction of a comprehensive system-design code. The competitiveness of the MTL design is demonstrated through mass and power comparisons with the SP-100 liquid metal-cooled reactor/Si-Ge thermoelectric generator power system.

Abstract: The problem of Beam Induced Stripping (BIS) process, occurring when a neutral beam propagates through the Earth's atmosphere, has been analyzed. At high current densities the process is important and leads to a rapid disintegration of the beam. At lower current densities currently contemplated for experiments, the effect is probably not significant.

King, R.J. et al. "Phenomenology of Microwave Coupling. Part I." Livermore, CA: Lawrence Livermore National Laboratory, November 1984. 91p.
Abstract: Recent advances in the development of high power microwave sources have increased the potential for future deployment of microwave weapons. A key ingredient in being able to predict the vulnerability of military systems to such threats involves understanding the phenomenology of how electromagnetic energy couples into cavity-like objects, or the so-called back-door coupling. A similar but much longer standing problem is that of nuclear electromagnetic pulses (EMP) in which the frequencies extend up to several hundreds of MHz. However, compared to EMP coupling, microwave coupling (from 1 GHz to above 40 GHz) is distinctively different because the wavelength is comparable to the size of the ports of entry (apertures, seams, cracks, protruding connectors, etc.). These ports of entry and the interior configuration of a vulnerable system are no longer below cutoff, and can permit significant penetration of the microwave energy into susceptible electronic systems. In fact, these coupling paths can be highly resonant at certain microwave frequencies, making the shielding against microwave threats difficult. This report summarizes the initial efforts at Lawrence Livermore National Laboratory to study the phenomenology of back door coupling at the low microwave frequencies (up to 2.5 GHz). These studies were limited to 2.5 GHz because the limitations of the Electromagnetic Transient Range Facility.

Abstract: A time dependent, fully electromagnetic particle code is used to simulate the current modulation in an intense relativistic electron beam (IREB) by an external rf source. It is shown that the intense beam may serve as a power amplifier with good phase stability, as suggested in earlier experiments. Increase in beam bunching by the DC space charge is demonstrated with a simple analytical model.

Abstract: This paper presents high-energy CW HF/DF chemical lasers developed under the U.S. Navy Sealite program and the Alpha program of the DARPA Triad program, and a brief account of Soviet chemical lasers. Continuous wave HF/DF chemical lasers were developed starting in the late sixties as high-power lasers of consistent interest to military circles. These are lasers that have the most matured technology among present-day high-energy lasers. It is hoped that in the near future CW HF/DF chemical lasers can be developed into a space laser weapon to deal with ICBMs. CW HF/DF chemical lasers are an integration of technologies in gas dynamics, chemistry, fluid chemistry, optics, and lasers. By using the branching chain reaction of heat liberation, inversion of the population ratio is generated to obtain lasers.

Abstract: Using rf pulse compression it will be possible to boost the 50- to 100-MW output expected from high-power microwave tubes operating in the 10- to 20-GHz frequency range to the 300- to 1000-MW level required by the next generation of high-gradient linacs for linear colliders. A high-power X-band three-stage binary rf pulse compressor has been implemented and operated at the Stanford Linear Accelerator Center (SLAC). In each of three successive stages, the rf pulse-length is compressed by half, and the peak power is approximately doubled. The experimental results presented here have been obtained at power levels up to 25-MW input (from an X-Band klystron) and up to 120-MW output (compressed to 60 nsec). Peak power gains greater than 5.2 have been measured.

LeClaire, R.J., Jr. "Beam Profile Effects on NPB Performance." Los Alamos National Laboratory, NM, March 1988. 20p.
Abstract: A comparison of neutral particle beam brightness for various neutral beam profiles indicates that the widely used assumption of a Gaussian profile may be misleading for collisional neutralizers. An analysis of available experimental evidence shows that lower peaks and higher tails, compared to a Gaussian beam profile, are observed out of collisional neutralizers, which implies that peak brightness is over estimated, and for a given NPB platform-to-target range, the beam current (power), dwell time or some combination of such engagement parameters would have to be altered to maintain a fixed dose on target. Based on the present analysis, this factor is nominally about 2.4 but may actually be as low as 1.8 or as high as 8. This is an important consideration in estimating NPB constellation performance in SDI engagement contexts.

Lee, R. et al. "Near Term Kinetic Energy Anti-Satellite Weapon System (KE-ASAT WS) Program. 1991 Electric Gun Tests, Test and Analysis Report: M1 Test Series." Livermore, CA: Lawrence Livermore National Laboratory, May 1992. 35p.
Abstract: The purpose of the electric gun tests was to investigate the effect of the impact of a thin membrane on materials of interest in 6--10 km/s, simulating the impact of a membrane the velocity range kill device on a satellite target. The impulse delivered to a satellite structure by such a collision must be known in order to design a membrane kill device for an anti-satellite weapon and to design the SELT tests which demonstrate the effect of broad-area impulsive loads on satellite structures. The impulsive load delivered to a structure by a membrane impact may exceed the momentum/area of the membrane because of rebound, blowoff of vaporized membrane material, and ejection of molten and fractured material from the target (impulse gain). It is important to quantify the impulse gain experimentally in the velocity range of interest. Also of interest is physical damage to the target including spall, melting and fracture. The electric gun facilities at LLNL are a unique resource for studying membrane impacts at hypervelocities. Velocitiesas high as 18 km/s have been demonstrated with thin Kapton membranes (flyer plates) of about 1 cm diameter, 0.3-mm-thickness; 6 km/s for 15-cm-square, 0.2-mm-thickness; and 4 km/s for 30.5-cm-square, 0.15-mm-thickness. Experiments are diagnosed with a full complement of diagnostics including electronic streak cameras, Fabry-Perot laser velocimeters, and flash x ray (FXR). Que proved to be the most useful because it was more accurate and did not suffer from edge effects. The impulse gain we measured was consistent with the predictions of simple theories. To understand and confirm the experimental results, one- and three-dimensional hydrodynamic simulations of the experiments were performed. The simulations were particularly useful in understanding the differences between experiments performed using the ballistic and wave-profile techniques.

Abstract: In addition to the initial transients designated as fast transient high-altitude EMP (HEMP) and intermediate time EMP, electromagnetic signals are also perceived at times from seconds to hundreds of seconds after a high-altitude nuclear burst. This signal has been defined by the term magnetohydrodynamic-electromagnetic pulse (MHD-EMP). The MHD-EMP phenomena has been both detected in actual weapon tests and predicted from theoretical models. This volume documents a preliminary research effort to investigate the nature and coupling of the MHD-EMP environments to electric power systems, define the construction of approximate system response network models, and document the development of a unified methodology to assess equipment and systematic vulnerability. The MHD-EMP environment is compared to a qualitatively similar natural event, the electromagnetic environment produced by geomagnetic storms.

Abstract: The magnetically insulated transmission line oscillator (MILO) is a high-power microwave device that combines the technologies of magnetically insulated electron flow and slow wave tubes. This combination makes the MILO a unique and robust device capable of operation over a wide range of voltages. MILOs are linear, two-conductor systems comprised of a cathode and an anode. The cathode is a smooth conductor. The anode consists of periodically spaced cavities. The system forms a slow wave transmission line capable of transmitting electromagnetic waves having phase velocities less than the speed of light (slow waves). MILO operation is initiated by charging the cathode to high voltage with respect to the anode. The large electric field on the cathode surface generates a plasma from which electrons are emitted. For sufficiently high voltage, the electrons are magnetically insulated from the anode and drift down the transmission line with substantial kinetic energy. A microwave generating instability occurs when the slow electromagnetic wave phase velocity is slightly less than the electron drift velocity when wave amplification occurs at the expense of electron energy. The dispersion relation is obtained by applying linear perturbation theory to Maxwell's equations coupled to equations for the electron equilibrium. Two models are used for the electron equilibrium: (1) thin-beam, and (2) relativistic Brillouin flow. The dispersion relation is numerically solved to obtain oscillation frequencies and growth rates of modes in the MILO.

Bellingham, WA: Society of Photo-Optical Instrumentation Engineers, 1989, p. 112-124.
Abstract: The magnetically insulated transmission line oscillator (MILO) is a high power microwave device that combines the technologies of magnetically insulated electron flow and slow-wave tubes. This combination makes the MILO a unique and robust device capable of operating over a wide range of voltages. Microwaves are generated in the MILO via an unstable interaction between slow electromagnetic modes and space-charge waves. A linear analysis of this microwave instability that includes the physics of magnetically insulated flow is presented. A dispersion relation is derived for TM modes in a cylindrical MILO. The dispersion relation is solved numerically to obtain the MILO frequency spectrum and instability growth rates. The linear theory results are compared with numerical simulation, and excellent agreement is obtained.

Abstract: Electronic warfare (EW) has emerged as a critical driving force in modern warfare. New generations of weapon systems directly impact EW requirements and strategies. Modern combat aircraft are faced with a drastic change of a possible threat scenario consisting of a mix of Western and Eastern weapon systems. The deployment of advanced pulse doppler radar systems in A/A and G/A application augmented by extensive electro-optic capabilities, directed energy weapons (laser or particle beam), and electromagnetic/shockwave weapons requires a detailed reassessment of NATO EW processes. The complexity and diversity of future threat scenarios necessitate changes in NATO EW system concepts, and an update of existing equipment including modifications of tactics and combinations of EW resources to improve survivability.

Liska, D. and L. Dauelsberg. "Design of High-Power Radio-Frequency Drive Loops for Operation into 425-MHz Linear Accelerators." Los Alamos National Laboratory, NM. April 1988. 20p.
Abstract: Recent designs for ultra high-frequency (UHF) band accelerators have prompted the need for high-powered drive loops compatible with the peak and average power needs of the accelerator tanks. Two such loops have been developed in the Accelerator Technology (AT) Division at Los Alamos and are now part of the general accelerator inventory. One loop is of small size, appropriate for radio-frequency quadrupole (RFQ) injector-accelerators, and is rated at 500-kW peak, 2-ms pulse length and 5% duty factor. The other loop is a 1-MW design, physically larger, also rated at 2-ms pulse length and 5% duty factor. The 1-MW drive loop uses a flat-disk ceramic window. The 500-kW loop as developed can use either a flat disk window or a special lambda2 window module available from Oak Ridge National Laboratory (ORNL). The purpose of this note is to describe the design of these loops and the tests performed on them so that they might be used by design engineers with appropriate applications.

Longtin, David R. and Michael G. Cheifetz. "Impact of Aerosol Forward Scattering on the ABL System." Scientific Report no.10. Lexington, MA: Sparta Inc., 20 December 1994. 47p.
Abstract: The AirBorne Laser (ABL) theater missile defense system involves the delivery of large amounts of highly focused energy across long, nearly horizontal paths in the upper troposphere and stratosphere. The current study addresses whether high amounts of aerosol forward scattering may impact ABL performance. The current study asserts that aerosol forward scattering effects are minimal for the ABL system and cannot account for the starlight scintillation behavior as measured by aircraft at ABL altitudes. Using appropriate scattering theories and numerical simulation techniques, the analysis considered possible contributions from the single scattering diffraction peak as well as multiple scattering near the optical axis. It was found that the characteristic scattering angles for background stratospheric aerosols and thin cirrus are too large, especially when compared with the transmitter divergence angles of the high energy laser and the tracking microradians to milliradians. Scattering energy is directed well away from the optical axis and, therefore, the energy received near on axis effectively equals the energy transmitted through the atmosphere. On-axis forward scattering effects become important for background stratospheric aerosols and thin cirrus only when scattering optical depths are on the 10 or greater.

Abstract: The Beam Experiments Aboard a Rocket (BEAR) flight rf control system has been completely designed and has been operated as a part of the flight accelerator system in the actual flight configuration. The accelerator has been vertically integrated onto the flight support structure (space frame) and has been operated in this configuration in preparation for the actual flight which is scheduled for late Spring, 1989. The rf control system consists of redundant voltage controlled oscillators, redundant amplitude controllers which maintain the proper fields in the RFQ, a frequency controller to maintain operation at the resonant frequency of the RFQ, and the necessary system monitors and interfaces required for the amplifiers, onboard system controller, and telemetry. The rf controller had to meet the electrical and environmental requirements while staying within its weight limit. This paper describes the final design of the rf controller and results from operation of the controller in its final flight configuration.
