Abstract: The design of the thermionic cathode grid-controlled high frequency gun and buncher cavity are presented as part of the system of the initial area of the injector (preinjector), of the fourth generation SKIF synchrotron developed in the Institute of Nuclear Physics (BINP). The technology of their manufacturing are described at the experimental production facility of the BINP. Besides, methods and results of high frequency system tests are also described. Estimated and measured characteristics of the high frequency cavities and features of their operation in the preinjector are analyzed.

Keywords: high frequency gun cavity, high frequency system manufacturing technology, electron beam welding, testing, high frequency test.
