A 56 MHz superconducting RF cavity was designed and installed in theRelativistic Heavy Ion Collider (RHIC). It is the first superconducting quarterwave resonator (QWR) operating in a high-energy storage ring. We discuss hereinthe cavity operation with Au+Au collisions, and with asymmetrical Au+He3collisions. The cavity is a storage cavity, meaning that it becomes active onlyat the energy of experiment, after the acceleration cycle is completed. Withthe cavity at 300 kV, an improvement in luminosity was detected from directmeasurements, and the bunch length has been reduced. The uniqueness of the QWRdemands an innovative design of the higher order mode dampers with high-passfilters, and a distinctive fundamental mode damper that enables the cavity tobe bypassed during the acceleration stage.
