Description
The 4th generation synchrotron light source SYLA is the flagship project of the new State light sources program of the Russian Federation. The SYLA will be constructed on the site of the NRC Kurchatov institute – IHEP in Protvino, Moscow Region. The SYLA will consist of both storage synchrotron and a free electron laser. The 6 GeV electron linac will be used for both injection into the synchrotron (top-up injection) and as a driver of short high-brightness electron bunches for the FEL. Two front ends will be developed and constructed for these purposes: the classical electron gun using a thermionic cathode for injection and the photogun to generate short ps bunches. The regular part of the e-linac will include more than 100 identical accelerating structures and will operate with both types of the electron beams.
Currently, the main components of the SYLA complex are being developed. The photogun test facility has been developed at MEPhI for the light source. It includes pi-mode accelerating structure with an energy of 7 MeV, photocathodes exchange chamber, laser system developed by IAP RAS and Avesta LLC, diagnostics chamber and all necessary engineering systems such as vacuum, focusing, adjustment, and thermostabilization, etc. All parts of the photogun test facility have been manufactured and installed and the test facility is now undergoing commissioning.
Main results of the photogun test facility development and commissioning will be presented in a report.
