Abstract
The current stage of development of powerful long-pulse free-electron laser (FEL) of the terahertz band carried out in the BINP RAS in collaboration with the IAP RAS based on the linear induction accelerator “LIU” with an energy of 5–10 MeV, a kA-level current, and a pulse duration of up to 200 ns is described. To ensure a stable narrow-band generation regime, the project proposes the use of two alternative types of the electrodynamic system: advanced Bragg resonators and quasi-optical Talbot-type resonators. We discussed design parameters of the FEL based on these resonators and results of their simulations under conditions of substantial oversize. Operability of resonators of the novel types was demonstrated in the “cold” electrodynamic tests.
