	The generator of high intensity monochromatic radiation in sub-mm band is currently under R&D at the Department of Electrophysical Facilities of MEPhI. This generator is based on photoinjector and irradiating Cherenkov capillary. It is necessary to have high brightness electron beams to generate of monochromatic radiation in this type of structure. These beams can be produced by photocathode and accelerated to energy of several MeV using short structure having high rate of energy gain. Irradiating capillary represents metal tube having inner radius of the radiation wavelength order and covered with dielectric layer or made of corrugated waveguide. It's important to study the self-consistent dynamics of the beam during the acceleration as the pulse current is equal several A, i.e. the beam dynamics should be studied taking into account RF (radiation) field and Coulomb field of self space charge. Another task is to study the electron beam dynamics and fields irradiated by it in decelerating structure in the absence of external fields. The scheme of the facility, its operation mode and high-current beam dynamics simulation results in accelerating and irradiating structures are presented.

The generator of high intensity monochromatic radiation in sub-mm band is currently under R&D at the Department of Electrophysical Facilities of MEPhI.

Irradiating capillary represents metal tube having inner radius of the radiation wavelength order and covered with dielectric layer or made of corrugated waveguide. It's important to study the self-consistent dynamics of the beam during the acceleration as the pulse current is equal several A, i.e. the beam dynamics should be studied taking into account RF (radiation) field and Coulomb field of self space charge.
