ADS注入器II的5MeV高能传输线的设计与搭建

Design and Setup of 5 MeV HEBT Line of the CIADS Injector Scheme II

ADS先导专项的注入器II计划在将质子束通过一个Cryomodule加速到5 Me V后,进行10 m A连续束流的调试,以验证ADS低能段的强流超导直线加速器技术。为了将50 k W的束流功率沉积到束流垃圾站,需要搭建一条高能束流传输线,从超导段开始传输束流。采用两套三组合四极透镜控制束流包络及垃圾站的束流尺寸,利用诊断真空室进行水平和垂直发射度的测量。为避免束流产生的真空管道损伤,该传输线必须确保束流无损失地传输到垃圾站。

A CW 10 m A, 5 Me V beam commissioning of CADS Injector II is planed recently to test the high power superconduction linac techniques. To transport 50 k W beam from linac to the beam dump, a high energy beam line（HEBT） line is designed and setup. Two Triplet are used to control the beam size along HEBT and at the beam dump. One diagnostics box is used for horizontal and vertical emittance measurement. To avoid damages to the vacuum pipe, beam should be transported to the beam dump without losses. The details of the HEBT design will be described in the paper.
