用高能质子辐照代替１２ＭｅＶ 电子辐照， 制造出ＫＫ２００Ａ 晶闸管。对辐照前后以及退火后的宏观电学参数测量发现， ３９ＭｅＶ 的质子辐照不仅能有效缩短晶闸管的关断时间， 提高工作频率， 还能有效修复制造过程中电压穿通的晶闸管， 并提高为快速晶闸管 High-energy proton irradiation instead of 12MeV electron irradiation, to create KK200A thyristor. Measurements of the macroscopic electrical parameters before and after irradiation and after annealing reveal that the 39MeV proton irradiation can not only shorten the thyristor turn-off time and improve the operating frequency, but also effectively repair the voltage-passing thyristor in the manufacturing process and improve Fast thyristor
