Electron beam heating of linear fusion devices

Ignition of linear high density solenoid fusion reactors by electron beams is a potential application of this high power, efficient technology in a relatively simple plasma system. Principal areas for investigation of this approach are beam deposition physics, diffusion of relativistic electrons across field lines by turbulence, beam and plasma stability, generation of high energy density beams and reduction of end loss rates. Physics of the generation, compression, and deposition of beams in such systems are discussed. Reactor operating modes and generator requirements are outlined.
