【摘要】 HI 13串列加速器加速管技术改造已经完成。用1根243 8cm和7根223 5cm的加速管替代了已使用16年之久的8根182 9cm加速管。为配合新加速管的安装,对加速器的主体布局进行了调整,对加速器的死区结构、充电系统、电阻分压系统进行了改造,重新设计制作了加速管入口栅网透镜及供电和控制系统,研制了新的输电梯死区惰轮。改造后的加速器头部电压达15 07MV。更多还原

【Abstract】 The accelerating tube upgrading on HI13 tandem accelerator at CIAE has been completed. The old 182.9 cm accelerating tubes which have been operated for more than 15 years were replaced by one 243.8 cm tube and seven 223.5 cm tubes. To accommodate the new tubes, the configuration of all elements along the beam axis inside tank was rearranged. The modifications on dead section structure, charging system and resistor dividing system has been made. The idlers for the laddertron charging system were redesigned and manufactured. A new structure of the gridded lens at the entrance of tube No.l and associated power supply and control system was adopted. The terminal voltage of the tandem accelerator is now promoted to 15.07 MV.更多还原
