The Linear IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) is aiming at demonstrating the low energy section of a 40 MeV/125 mA IFMIF deuteron accelerator up to 9 MeV with a full beam current in cw operation. For such a high-power beam, the LIPAc injector is required to produce a 100 keV D+ beam with 140 mA and match it for injection into the Radio Frequency Quadrupole (RFQ) accelerator. The injector is designed by CEA-Saclay based on the high intensity light ion source (SILHI). In 2019, the commissioning of the RFQ to demonstrate the D+ beam acceleration at a low duty cycle (0.1%) was conducted. A nominal beam current of 125 mA D+ beam was accelerated up to 5 MeV through the RFQ successfully. The LIPAc injector fully satisfied the requirements for RFQ beam commissioning at the pulse mode.

为国际聚变材料辐照设施的原型加速器调试高电流 H+/D+ 离子束

线性 IFMIF（国际聚变材料辐照设施）原型加速器 (LIPAc) 旨在展示高达 9 MeV 的 40 MeV/125 mA IFMIF 氘核加速器的低能量部分，并在连续工作中使用全束流。对于如此高功率的光束，LIPAc 注入器需要产生 140 mA 的 100 keV D+ 光束，并将其匹配以注入射频四极杆 (RFQ) 加速器。注射器由 CEA-Saclay 基于高强度光离子源 (SILHI) 设计。2019 年，进行了 RFQ 的调试，以演示低占空比 (0.1%) 下的 D+ 光束加速度。125 mA D+ 光束的标称光束电流通过 RFQ 成功加速至 5 MeV。LIPAc 喷射器完全满足脉冲模式下 RFQ 光束调试的要求。
