Studies on Electron Beam Transport in a Linear Induction Accelerator for Free Electron Laser Application

Project of submillimeter free electron laser (FEL) is developed at BINP in collaboration with IAP [1] . The FEL scheme is based on a high current electron beam (E e = 5−20 MeV, I b = 1−2 kA, τ= 160−200 ns) generated at the new linear induction accelerator (LIA) [2] , [3] . According to our theoretical analysis, such beam allows us to generate coherent pulses of submm-radiation in the frequency range 0.3-1 THz. The radiation power in such scheme can reach a sub-megawatt level and the energy content up to ~100 J.
