北京大学设计的耦合RFQ-SFRFQ(CRS)腔是将射频四极杆(RFQ)和分离功能射频四极杆(SFRFQ)结构耦合到单个腔中的新型直线加速器。用于 CRS 腔的升级氦注入器由 2.45 GHz 永磁电子回旋共振 (ECR) 离子源和 1.16 m 低能束传输 (LEBT) 组成,现已构建并测试。注入器的光束条件经过精心优化,以满足 CRS 直线加速器的要求,开发了相应的控制系统和二维扫描仪代码 CRSv1.0,以优化从 LEBT 部分到 CRS 腔入口的光束传输。光束传输效率达到约87.5%,并通过扫码获得了优化的工作参数。
The coupled RFQ–SFRFQ (CRS) cavity designed in Peking University is a new type linac that coupled radio frequency quadrupole (RFQ) and separated function radio frequency quadrupole (SFRFQ) structure into a single cavity. An upgraded helium injector for the CRS cavity consisting of a 2.45 GHz permanent magnet electron cyclotron resonance (ECR) ion source and a 1.16 m low energy beam transport (LEBT) has been constructed and tested. The beam conditions of the injector were carefully optimized to satisfy the requirements of the CRS linac, the corresponding control system and a two-dimension scanner code CRSv1.0 were developed for optimizing the beam transmission from LEBT section to the entrance of the CRS cavity. The beam transmission efficiency has reached to approximately 87.5% as well as the optimized operating parameters were obtained by means of the scanner code.
