Research Abstract

電子ビーム形多価イオン源(EBIS)の製作を完成し(平成7年9月)、電気通信大学レーザー極限技術研究センターに設置した。本体の真空排気を行い、液体ヘリウムの過冷却による真空度向上を観測し、超多価イオン生成への指針を得た。3T-4.5Tの超強磁場中に電子ビームを打ち込み、コレクターでの100%回収が達成されるべく、電子ビーム発生、輸送の試運転を行った。その結果、10KeV10mAから、90KeV100mAまでの電子ビームに対して、設計通り輸送できていることを確認した。また、固体X線検出器を用いて、タングステンの64価イオンがイオントラップ部に生成、蓄積されていることを観測し、この装置の設計製作が当初の設計目標を満たして完成、終了したことを確認した。
