Development of Intense Proton Source and LEBT System in Compact Pulsed Hadron Source

  • 摘要: 清华大学为微型脉冲强子源加速器注入研制了一套2.45 GHz ECR强流脉冲质子源和低能传输线(LEBT)系统。质子源采用四电极系统引出能量达50 keV/75 mA的混合束,经低能传输段实现匹配注入RFQ加速器。在LEBT出口处获得了高达50 keV/60 mA的质子束,使用Allison发射度探测器在第2诊断室测得均方根归一化发射度小于0.2 πmm•mrad。本文介绍强流质子源与低能传输段的调试结果,并对束流品质进行了研究。

     

    Abstract: A 2.45 GHz intense pulsed ECR proton source and low energy beam transport (LEBT) system was developed by Tsinghua University for the compact pulsed hadron source (CPHS). The proton injector provides proton beam into a 3.2 MeV RFQ accelerator. The 50 keV/75 mA hybrid beam extracted by a 4-electrode extraction system from the ion source passes through the LEBT to the RFQ entrance and the root-mean-square (RMS) normalized emittance is less than 0.2 πmm•mrad. The commissioning results of the intense proton source and low energy beam transport system were described in this paper. The beam quality was also studied.
