Abstract :
Using a superconducting LEP (Large Electron Positron Collider) prototype cavity, an e+ beam was accelerated at Ea=5.5 MV/m. The SPS (Super Proton Synchrotron) proton accelerator/proton-antiproton collider/LEP injector was chosen for the implementation of the cavity. After 8000 h at 4.5 K Eamax remained unchanged (7.1 MV/m); the Q-value (5 MV/m) was 2/3×109. No major system failure occurred. RF feedback guaranteed very low fluctuations of the cavity field amplitude and phase
