Injection System for the Siberian Ring Source of Photons

The Siberian ring source of photons (SKIF) is a new 3-GeV fourth-generation source of synchrotron radiation with a perimeter of 480 m that is being developed in Novosibirsk. To obtain bright synchrotron-radiation beams, the SKIF must have a suitable injection system for the preparation of intense electron beams. The article describes the proposed configuration of the injection system and its parameters. Electron bunches are produced by a thermal gun based on a radio frequency cavity. Then they are accelerated to 200 MeV in a linac and accelerated to 3 GeV in a booster synchrotron with a perimeter of 160 m. The injection complex will operate at a frequency of 1 Hz and will be able to pump the main storage ring with a current of up to 400 mA in one minute.
