A High-Power S-Band RF Window for a Klystron

Abstract

The calculation, measurements, and testing of a vacuum RF S-band window are described. Vacuum waveguide pillbox-type RF windows at a frequency of 2856 MHz, which were developed and manufactured at the works of the Budker Institute of Nuclear Physics (BINP), make it possible to replace the RF windows of the klystrons that are used in the injection complex of the BINP and can be applied in new designs in the fields of both RF-power sources and accelerator techniques. Tests were performed using 35-MW pulsed power and a pulse duration of 3.8 μs.
