摘要

利用超导LEP(大型电子正电子对撞机)原型腔，以e/ sub /=5.5 MV/m的速度加速了e/sup +/束流。采用SPS (Super Proton Synchrotron)质子加速器/质子反质子对撞机/LEP注入器实现腔体。在4.5 K下，8000 h E/sub //sup max/保持不变(7.1 MV/m);q值(5 MV/m)为2/3*10/sup /。未发生重大系统故障。射频反馈保证了腔场振幅和相位的极低波动。

Long-term test of a LEP prototype superconducting cavity in the CERN SPS

Using a superconducting LEP (Large Electron Positron Collider) prototype cavity, an e/sup +/ beam was accelerated at E/sub a/=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 E/sub a//sup max/ remained unchanged (7.1 MV/m); the Q-value (5 MV/m) was 2/3*10/sup 9/. No major system failure occurred. RF feedback guaranteed very low fluctuations of the cavity field amplitude and phase.<>
