【摘要】 基于合肥光源提供的铜制有源高频腔和上海光源提供的铌制超导无源高频腔,设计了可以测量高频腔性能参量的实验装置.以探针将微波信号馈入高频腔体中,通过网络分析仪接收到的信号分析微波在腔体中的谐振情况,从而测量腔体的特性.利用该实验装置测量了2个高频腔的谐振频率、品质因数和腔体中心轴线上的电场分布.更多还原

【Abstract】 A platform for the measurement of the performance parameters of two radio-frequency cavities,provided by National Synchrotron Radiation Laboratory(NSRL) and Shanghai Synchrotron Radiation Facility(SSRF),was set up,respectively,among which one was a coppery active cavity,and the other was a superconductive passive cavity.Both cavities were put under measurement,and their resonance frequencies,quality factors and distributions of electric fields were measured.更多还原
