Abstract

The BNL 704MHz SRF gun has a grooved choke joint to support the photo-cathode. Due tothe distortion of grooves at the choke joint during the BCP for the choke joint, severalmultipacting barriers showed up when it was tested with Nb cathode stalk at JLab. We builta setup to use the spare large grain SRF cavity to test and condition the multipacting atBNL with various power sources up to 50kW. The test is carried out in three stages: testingthe cavity performance without cathode, testing the cavity with the Nb cathode stalk thatwas used at Jlab, and testing the cavity with a copper cathode stalk that is based on thedesign for the SRF gun. This paper summarizes the results of multipacting simulation, andpresents the large grain cavity test setup and the test results.
