The horizontally scanning, multi-angle charge-exchange analyser on the Poloidal Divertor Experiment (PDX) was used to study the beam ion slowing-down process with high-power perpendicular injection. Measurements were made over a wide range in toroidal field (8 kG <BT<22 kG), plasma current (200 kA <Ip<500 kA), and beam power (1 MW <PB<7 MW). In MHD-quiescent plasmas, agreement is found between the measured slowing-down spectra and theoretical predictions as a function of both angle and energy. Classes of prompt orbit losses are observed with both co-and counter-injection which have been understood and applied to plasma diagnostics.

ポロイダルダイバータ実験(PDX)における水平走査型多角度荷電交換分析器を用いて、高パワー垂直入射時のビームイオン減速過程を研究した。測定は、トロイダル磁場(8 kG < BT < 22 kG)、プラズマ電流(200 kA < Ip < 500 kA)、およびビームパワー(1 MW < PB < 7 MW)の広い範囲にわたって行われた。MHD静的プラズマにおいて、測定された減速スペクトルは、角度およびエネルギーの両方の関数として理論スペクトルと一致することが見出された。同方向および逆方向入射の両方において、即時軌道損失のクラスが観測され、これらは理解され、プラズマ診断に応用された。
