溅射超导腔作为超导重离子直线加速器的重要部件,在组装前需测量其超导性能,为此需建立1套单腔柜系统。通过对单腔柜内真空监测、冷屏预冷以及液氦罐装,使超导腔处于4.2K的低温状态;然后控制马达对机械调谐器和功率耦合器进行调整,以改变腔体频率和耦合程度,从而测量超导腔性能。该项目正在进行中,2010年的主要进展如下。
Sputtering superconducting cavity as an important part of superconducting heavy ion linear accelerator, the need to measure the superconducting properties before assembly, for which a single chamber cabinet system needs to be established. Through the vacuum monitoring of the single-chamber cabinet, cold-screen pre-cooling and liquid helium canning, the superconducting chamber is at a low temperature of 4.2K; then the motor is controlled to adjust the mechanical tuner and the power coupler to change the cavity frequency and Coupling degree to measure superconducting cavity performance. The project is under way and the main developments in 2010 are as follows.
