国家空间中子源(NSNS)前端加速器包括一个65 keV的LEBT,一个2.5 MeV的质子束和一个匹配的加速55 mA的H束,占空比为6%。关键的设计问题是6%的光束占空因数,5自由空间波长长402.5 MHz的斩波,纳秒斩波的光束进入第一DTL之前。前端系统的概念设计,将提出一些拟议的子系统的实验验证。
The National Spallation Neutron Source (NSNS) front-end accelerator comprises a 65 keV LEBT, a 2.5 MeV RFQ and a matching accelerating a 55 mA H beam with a 6% duty factor. Critical design issues are the 6% beam duty factor, the 5 free space-wavelength long 402.5 MHz RFQ, and nanosecond chopping of the beam before it enters the first DTL. The conceptual design of the front-end systems will be presented, with experimental validation of some of the proposed subsystems.
