Abstract

Currently, the NRC «Kurchatov Institute» in collaboration with partners is developing the 4th generation synchrotron light source SYLA (Synchrotron + Laser) with an energy of 6 GeV. This facility will consist of a source based on a storage ring and a free-electron laser (FEL). As one of the options, a radiofrequency (RF) gun with a photocathode will be used to generate short high-brightness electron bunches for the FEL. The gun structure is composed of 3.5

π

-mode standing wave accelerating cells at operating frequency of 2800 MHz with a coaxial RF coupler.

Previously, beam dynamics simulation, optimization of electrodynamic characteristics and thermal processes analysis were performed. So far, the manufacturing of the RF gun has been completed. The report presents the results of measurements of the prototype (the operating frequency, the axis electric field, quality factor).

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
