Development of the MHz repetition bipolar pulse induction acceleration system

  • 摘要: 采用感应同步加速原理,能在MHz重复频率下连续运行的双极性脉冲感应加速单元可以替代传统的射频加速单元应用于环形加速器中。针对MHz重频双极性脉冲功率源设计、感应腔负载特性等关键技术开展了实验研究,研制了一套MHz重频双极性脉冲感应加速单元。相比于日本高能加速器研究机构(KEK)研制的感应同步加速单元,该加速单元对电路结构进行了优化, 在加速脉冲具备相同顶降的前提下,将加速腔纵向尺寸缩小了5倍以上,可有效改善现有脉冲感应加速单元在加速电压调节方面的局限性,提高了功率系统的稳定性,减小了组元连续运行时的功率损耗,更加适应各类环形加速器对重频脉冲感应加速组元的应用需求。
