内容記述 |
The Linear IFMIF Prototype Accelerator (LIPAc) is being commissioned under the Broader Approach agreement between Europe and Japan, with the aim of validating the low-energy section of the accelerator for the International Fusion Materials Irradiation Facility (IFMIF). LIPAc is designed to accelerate a 125 mA deuteron beam up to 9 MeV in continuous-wave (CW) operation. This paper reports the outcomes of high-duty cycle beam commissioning at 5 MeV using the RFQ referred to as Phase B+. In this phase, a maximum duty cycle of 8.75% and a beam current of 119 mA were achieved. This corresponds to an average beam power of 40–45 kW, which is the highest beam power among operational RFQs. It was also identified that the RFQ RF couplers are a bottleneck for further duty cycle increases, leading to the preparation of brazed high-duty couplers. These achievements establish a solid foundation for the next commissioning phase, which will include SRF Linac commissioning and aim for CW operation to demonstrate the IFMIF accelerator concept. |
