Accelerator Complex based on Photoinjector at IAP RAS towards Generation of High-power Radiation from Terahertz to X-rays

At the Institute of Applied Physics RAS, a photoinjection electron accelerator is being developed, in which a step-by-step acceleration of particles up to an energy of about 20 MeV should be provided. The first 3.5 MeV section of the accelerator can be used to experimentally study promising regimes of terahertz radiation of short electron bunches. The low emittance bunches additionally accelerated in the second section are planned to be used for injection into the plasma accelerator system for the subsequent increase of the energy to a GeV level. In addition, work is underway to study new promising options for photocathodes.
