对BEPCII超导腔的输入耦合器进行了大功率调节。室温调节后，驻波模式下连续波的150kw射频功率顺利通过耦合器。同时，还研究了一系列提高光束运行过程中耦合器性能的方法。到目前为止，该输入耦合器可以在2.5 GeV下稳定地提供高达100 kW的射频功率，电流为250 mA。
High power conditioning of the input coupler for BEPCII superconducting cavity has been performed. After room temperature conditioning, the RF power of 150 kW with continuous wave at standing wave mode passed through the coupler without any problem. Meanwhile, a series of methods have also been studied to improve the performance of the coupler during the beam operation. Up to now, the input coupler can feed a RF power up to 100 kW stably with high current of 250 mA at 2.5 GeV.
