Abstract
A 1 GHz 9-cell superconducting cavity was installed and tested in the PETRA electron-positron storage ring. 2 mA were injected at 7 GeV and stored by a superconducting cavity with a maximum gradient of 2.5 MV/m. With the addition of normal-conducting 500 MHz cavities the superconducting cavity transferred 27.5 kW to a 8 mA beam current. The resonator is kept at LHe temperature since February 1985 to gain long-time experience on superconducting cavities in the storage ring environment. The maximum achievable field and the quality factor have not changed up to now.
