Physical design of the Dragon-I linear induction accelerator
摘要
介绍了 "神龙一号"直线感应加速器物理设计的主要考虑."神龙一号"加速器是一台电子直线感应加速器,由3.6MeV感应迭加型注入器、72个感应加速腔、脉冲功率系统、束流输运和聚焦系统、控制系统和真空、绝缘油、绝缘气体以及去离子水系统组成.能产生20MeV、束流大于2.5kA,脉冲宽度为60ns的强流脉冲电子束,X光焦斑均方根直径为1.5mm.
Abstract
This paper describes the design considerations of the DragonI linear induction accelerator (LIA) at Institute of Fluid Physics, China Academy of Engineering Physics. The DragonI facility is an electronic linac and consists of a -2.0MV/+1.5MV bipolarity inductive adder injector, 72 accelerating cavities, pulsedpower system, beamtransport, control and auxiliary systems. It can produce an electron beam of 3kA, 20MeV with pulse width of 90ns (FWHM). Good accelerating voltage pulse for each cavity with width of 120ns (FWHM) and up to 60ns flattop within ±1% variation has been obtained for high beam quality.
