Note (General): ITER中性粒子入射加熱装置(NBI)用負イオン加速器には、単孔単段型(SINGAP: Single-aperture single-gap)と多孔多段型(MAMuG: Multi-aperture multi-gap)の2方式が提案されており、前者はCEAカダラッシュ研究所、後者は原子力機構において開発が進められてきた。ITER NBI建設に向け、両者の性能を比較することを目的とした試験をITERタスクとして行うこととなり、SINGAP加速器を原子力機構のMeV級イオン源試験装置に取り付けてMAMuG加速器と同じ設備,計測システムで性能評価を行った。その結果、耐電圧性能,最大負イオンビーム電流,付随電子加速の観点からMAMuGが優れることが明らかとなり、ITER機構との協議の結果、ITER NBIにはMAMuG方式が採用されることになった。
For the ITER NBI, two accelerator concepts have been proposed. One is the SINGAP (single gap single aperture) developed at CEA Cadarache and the other is the MAMuG (Multi aperture multi gap) developed at JAEA. In order to assess the performance of the SINGAP and the MAMuG concepts at the same test facility under the same diagnostics, a collaborative test was performed between JAEA and CEA Cadarache under an ITER task agreement. For this purpose, the SINGAP accelerator was installed at the MTF of JAEA. From the viewpoint of voltage holding, maximum beam current and electron acceleration, the MAMuG showed better performance than the SINGAP, and it has been decided to choose the MAMuG as the baseline accelerator for the ITER NBI.
