论文摘要
众所周知,需要长的射频四极加速器的调整。这项研究调查了如何实现具有多个较短和独立空腔的有效长RFQ加速器。从RF的角度来看,较短的空腔的使用具有许多优势,例如放大的模式分离和简化的RF调整,但是腔之间的光束匹配将成为一个问题,尤其是在高电流和低能下。以9 m长的高电流机器为例,本文介绍了整个多级RFQ加速器的设计概念和方法。
It is well known that the tuning of a long radio-frequency quadrupole accelerator is demanding. This study investigated how to realize efficient long RFQ accelerators with multiple shorter and independent cavities. From the RF point of view, the use of shorter cavities has many advantages e.g. enlarged mode separation and simplified RF tuning, but the beam matching between cavities will become an issue, especially at high current and low energy. Taking a more than 9 m long, high current machine as an example, this paper presents the design concepts and methods leading to good beam quality and high beam transmission throughout a multi-stage RFQ accelerator.
