Development of Photoinjector Accelerator Complex at the Institute of Applied Physics of the Russian Academy of Sciences: Research Status and Prospects

This work is devoted to the studies performed at the Institute of Applied Physics of the Russian Academy of Sciences and aimed at the development of the photoinjector accelerator complex, which ensures formation of the electron bunches with charges of up to 100 pC and particle energies of 3 to 5 MeV. The key elements of the complex are described, namely, the accelerating cavity powered by the klystron with an operation frequency of 2.45 GHz and a power of 5 MW, a photocathode based on diamond films, a high-power ultraviolet laser, and a system for synchronizing the laser pulses with the phase of the accelerating microwave field. The design parameters of the components of the complex are presented, and the state of research related to its realization is discussed.
