During the EVEDA (engineering validation and engineering design activities) phase of the International Fusion Materials Irradiation Facility (IFMIF) project, a 125 mA/9 MeV linear prototype accelerator (LIPAc) has to be built, tested and operated in Rokkasho-mura (Japan). Involved in this project for several years, CEA-Saclay designed the injector of this accelerator which is composed of an electron cyclotron resonance ion source, delivering a 140 mA deuteron beam at 100 keV, and a low energy beam transport (LEBT) line to match the beam for the injection into the radio-frequency quadrupole. In this paper, the components of the LIPAc injector are described.The commissioning of the ion source and LEBT with beam started in November 2014. The different phases of the commissioning are explained and some noticeable experimental results obtained with a beam at 100 keV are presented.

国際核融合材料照射施設(IFMIF)プロジェクトのEVEDA(工学的検証および工学的設計活動)フェーズにおいて、125 mA/9 MeVの線形原型加速器(LIPAc)が六ヶ所村(日本)で建設、試験、運転されることになっている。このプロジェクトに数年にわたり関与してきたCEA-サクレーは、この加速器の入射器を設計した。入射器は、100 keVで140 mAの重陽子ビームを供給する電子サイクロトロン共鳴イオン源と、高周波四重極への入射のためにビームを整合させる低エネルギービーム輸送(LEBT)ラインで構成される。本論文では、LIPAc入射器の構成要素について述べる。イオン源およびLEBTのビームを用いた試運転は2014年11月に開始された。試運転の各段階について説明し、100 keVのビームで得られた顕著な実験結果のいくつかを提示する。
