Free Electron Laser (FEL) Animations and tutorials
Naval Defense
The Following animation is a demonstration of how a free electron works. Next it shows how FEL's can be put into carriers. Finally the animation shows four different engagement scenarios that the FEL is well suited for.
Phase Space Diagram
This video illustrates the use of phase space to illustrate velocity / angle. the resulting phase space plot is called a separatrix. it is the optimal profile for this type of graph.
Electron Energy in Phase Space
The following plot shows electron energy in a phase space diagram. this type of modeling is used to illustrate energy gained and lost in the system.
