Abstract

A travelling wave resonant ring has been developed at Bhabha Atomic Research Centre (BARC) to test 325 MHz radio frequency (RF) power couplers for accelerator cavities. It mainly consists of half height rectangular waveguide components. The ring has been tested for output power of 30 kW with gain of 14.4 dB. Presently, RF characterization and high power testing has been completed without RF couplers. The design, RF simulations and characterization of the entire ring, along with the high power test results, are presented in this paper.
