Description
Xeガスを用いるビーム電流試験
グラファイトアークチャンバを有するBernasイオン源を使用した。ビーム条件は以下の通りであった。アーク電圧:50V、アーク電流:0.75A、引出し電圧:20kV、抑制電圧:3kV。使用された不活性ガスはアルゴンであり、1sccmまたは1.5sccmのいずれかの速度でアークチャンバに流し込まれた。フッ素含有ガスは2%のガス混合物(Ar+NF3)において使用されたNF3であり、(1sccmのAr流れにおける)0.021sccmまたは(1.5sccmのAr流れにおける)0.031sccmのいずれかの流量に対応する。ガス流を記録しながらアークチャンバを合計11時間運転し、各供給源を検査して、運転期間に続いてフィラメント重量を測定した結果を表1に示す。
