Vinokurov The new radiofrequency (RF) gun making an intensive high-quality electron beam for injecting in Novosibirsk microtron recuperator (ERL) and driving Free Electron Laser (FEL) is made in Budker INP SB RAS. Bench tests of RF gun demonstrated good results in strict accordance with the calculations predicting average current of a bunch of 100 мА, energy of particles of 400 keV and normalized emittance less than 15 microns. The RF gun stand testing showed reliable work, unpretentious for vacuum conditions and stable in long-term operation. The additional injection beamline built-in to the existing system of the NovoFEL injector with the static gun is developed and designed.
