Michael Lynch, William Reass, Daniel Rees, Amy Regan, Paul Tallerico

摘要:

SNS直线加速器将2 mA的平均束流加速到968 MeV的能量。直线加速器的脉冲频率为60 Hz,H-束脉冲为1 ms。直线加速器的第一个185 Mev使用正常导电腔,直线加速器的其余长度使用超导腔。直线加速器的工作频率为402.5 MHz,最高可达87 MeV,其余部分则变为805 MHz。本文概述了直线加速器射频系统。概述包括高功率RF组件、HV转换器/调制器和RF控制的描述和配置。将讨论RF系统中的问题和权衡,特别是关于脉冲超导腔的使用。

英文摘要:

The SNS linac accelerates an average beam current of 2 mA to an energy of 968 MeV. The linac is pulsed at 60 Hz with an H- beam pulse of 1 ms. The first 185 Mev of the linac uses normal conducting cavities, and the remaining length of the linac uses superconducting cavities. The linac operates at 402.5 MHz up to 87 MeV and then changes to 805 MHz for the remainder. This paper gives an overview of the Linac RF system. The overview includes a description and configuration of the high power RF components, the HV converter/modulator, and the RF controls. Issues and tradeoffs in the RF system will be discussed, especially with regards to the use of pulsed superconducting cavities.
