The power cou­pler is de­vel­op­ment at Korea Uni­ver­sity for a Sin­gle Spoke Res­onator (SSR) of heavy ion ac­cel­er­a­tor. Our power cou­pler is a coax­ial ca­pac­i­tive type based on a con­ven­tional 3-1/8 inch elec­tronic in­dus­tries al­liance (EIA) 50 Ω coax­ial trans­mis­sion line with a ti­ta­nium ni­tride (TiN) coated sin­gle ce­ramic win­dow. A high power test is rec­tan­gu­lar test cav­ity with high vac­uum and var­i­ous mea­sur­ing equip­ment, such as an arc de­tec­tor, a power meter, and an elec­tron pick-up probe. The in­ter­lock sys­tem under vac­uum and arc in­stru­men­ta­tions pre­vent the RF win­dow from break­ing the power cou­pler win­dow dur­ing the high power test. We con­duct high power tests for more than 12 hrs at 12 kW in a 325 MHz con­ti­nous wave (CW) mode to ver­ify the per­for­mance of the de­signed power cou­pler.
