Design of RF generator at cooling storage experimental ring

Abstract

对兰州重离子加速器冷却储存环实验环(CSRe)的高频系统功率源的设计作了详细的工程计算,工作频率范围为0.5～2.0MHz,工作于基波及二次谐波模式,发射机不仅能工作于点频连续波模式,而且还可以工作在扫频调制模式,输出最大功率达到70kW。满足最高加速或减速电压10kV的设计要求,能够用于捕获放射性次级束并将束流的能量从400MeV/u减速到30MeV/u。<span style="color: rgb(51, 51, 51); font-family: arial, helvetica, sans-serif; font-size: 13px; line-height: 22px; background-color: rgb(248, 248, 248);">RF system of HIRFL-CSRe(cooling storage experimental ring) was designed by ourselves and manufactured domestically, which operates in the frequency range of 0. 5~2. 0 MHz at first and second harmonic modes. Based on detailed engineering calculation, the design of RF generator was completed. It will work not only in CW mode but also in the mode of ramping pulse modulation, and the maximum power is up to 70 kW. It satisfies the requirement of 10 kV maximum deceleration voltage to capture the irradiative beam and decelerate the beam from 400 MeV/u to 30 MeV/u.</span
