abstract = {{Project of high-power long-pulse THz-band FEL is under development in collaboration between BINP (Novosibirsk) and IAP RAS (N.Novgorod) driven by the linac LIU 5 - 20 MeV / 2 kA / 200 ns. The aim of this project is to achieve a record sub-GW power level and pulse energy content up to 10 - 100 J at THz frequencies. Principal problems in realization of this generator include: formation of the electron beam with parameters acceptable for operation in the short-wavelength ranges, development of undulator for pumping operating transverse oscillations in the beam, and elaboration of electrodynamic system that can provide stable narrow-band oscillation regime in a strongly oversized interaction space. Initial proof-of-principle experiments are planned to start at the LIU-5 accelerator in the 0.3 THz frequency range, with prospects of transition to 0.6 THz range and higher frequencies after positive results would be demonstrated. In the report, the design parameters of the FEL project are discussed. Results of electron-optical experiments on the beam formation are presented. Structural elements of the FEL magnetic system based on helical undulator and a guide solenoid that provides intense beam transportation were elaborated. An electrodynamic system was proposed exploiting advanced Bragg structures, which have significantly improved selective properties. Structures of such type were designed with the diameter of 20 and 40 wavelengths for operation in specified frequency ranges.}},
