Development of photoinjector in IAP RAS

A photoinjector electron accelerator is being developed at the Institute of Applied Physics of the Russian Academy of Sciences, in which it is planned to implement sequential acceleration of particles up to energies of about 20 MeV. The first section of the complex, designed for an output particle energy of 3.5 MeV, can be used for experimental study of promising regimes of terahertz radiation from short electron bunches. After additional acceleration in the second section, bunches with small transverse emittance and velocity spread can be injected into a plasma accelerator cell to further increase their average energy to the GeV level and to use them as an active medium in an X-ray FEL. In addition, work is underway to study photocathodes based on diamond films.
