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 continuous-wave operation. For such a high-power beam, the LIPAc injector is required to produce a beam current of 140 mA and 100 keV D+ beams. The injector commissioning to reach high beam current has been progressing at high duty cycle operation, then stable operation for many hours at a beam condition of 150 mA total extracted current. This result demonstrates that the LIPAc injector can meet the required performance for nominal 125 mA long pulse deuteron beam acceleration.

リニアIFMIF(国際核融合材料照射施設)原型加速器(LIPAc)は、40 MeV/125 mA IFMIF重陽子加速器の低エネルギー部を、連続波運転において全ビーム電流で9 MeVまで実証することを目指している。このような高パワービームにとって、LIPAc入射器は140 mAのビーム電流と100 keVのD+ビームを生成することが要求される。高ビーム電流に到達するための入射器コミッショニングは高デューティサイクル運転で進められ、その後、150 mAの全引き出し電流のビーム条件で数時間にわたる安定運転が達成された。この結果は、LIPAc入射器が公称125 mA長パルス重陽子ビーム加速に要求される性能を満たし得ることを実証している。
