摘要

SARAF第二阶段低温直线加速器(linac)目前正在建设中，并将通过SNRC和CEA的合作努力投入使用。直线加速器将加速5ma脉冲/连续波(CW)质子束和氘核束，分别达到35mev和40mev的能量。直线注入器由第一阶段组件组成，包括ECR离子源、低能量束传输(LEBT)线路和四杆射频四重器(RFQ)。此外，还安装了一条新的中能量束传输(MEBT)线，并将其集成到注入器基础设施中。MEBT包括三个共振器、磁光元件和光束诊断。MEBT光束诊断以及安装在下游的I期d板用于光束表征。下游安装的临时波束线(TBL)和镓铟液体靶(GALIT)的原型用于调试，在高波束占空比下运行，包括连续波模式。该报告描述了计划于2023年下半年交付低温模块之前喷射器的质子束调试过程。

Beam commissioning of the SARAF Injector and MEBT (protons)

The SARAF Phase II cryogenic linear accelerator (linac) is currently under construction and will be commissioned through collaborative efforts between SNRC and CEA. The linac will accelerate a 5 mA pulsed/continuous wave (CW) proton and deuteron beam, reaching energies of up to 35 MeV and 40 MeV, respectively. The linac injector consists of Phase I components, including an ECR ion source, a Low-Energy Beam Transport (LEBT) line, and a 4-rod Radio Frequency Quadruple (RFQ). Additionally, a new Medium Energy Beam Transport (MEBT) line has been installed and integrated into the injector infrastructure. The MEBT includes three rebuncher resonators, magneto-optical elements, and beam diagnostics. The MEBT beam diagnostics, as well as the Phase I D-plate installed downstream, were used for beam characterization. The downstream-installed Temporary Beam Line (TBL) and a prototype of the Gallium Indium Liquid Target (GALIT) were used for commissioning, operating at high beam duty cycles, including CW mode. The report describes the proton beam commissioning process of the injector prior to the delivery of the cryomodules, scheduled for the second half of 2023.
