The electron beam of the linear induction accelerator with kiloampere current as a driver for the submillimeter free electron laser

The project of a submillimeter free electron laser (FEL) based on a relativistic electron beam (REB) generated in a linear induction accelerator (LIA) was proposed at the BINP SB RAS together with the IAP RAS. According to our theoretical analysis, the electron beam generated in the LIA (energy \({{E}_{e}} = 5{\text{--}}10\) MeV, current \({{I}_{b}} = 1{\text{--}}2\) kA, normalized emittance \({{\varepsilon }_{n}}\) ~ 1100 π · mm · mrad) is a suitable driver for generating sub-GW pulses of coherent EM radiation in submm range (0.3–1 THz). The main proposals for the creation of the FEL based on the electron beam generated in the LIA are presented, the main project tasks are outlined, and the proposed methods for their solution are described. The results of electron-optical experiments on the formation of an electron beam intended for FEL applications are presented.
