プラズマ定常維持のための密度制御システムの開発/現在までに、QUEST装置では１０分を優に超える放電を達成しているが、その際の燃料供給方法として、密度信号の代替としてHa信号を参照しながら水素を供給するというものであり、直接的に密度信号を参照してないため厳密な意味での密度制御ではない。そこで、干渉計の信号をリアルタイムに解析してプラズマ密度を算出して、その密度信号を参照して燃料を供給するシステムを開発し、プラズマ定常維持のための密度制御を行うことを目的とする。

共同研究

FPGAを利用した高速平衡計算コードの開発/トカマク装置において高性能プラズマを定常維持するためには、プラズマの位置形状をリアルタイムに同定を行い、その制御を行うことが望ましい。従来のQUEST装置では、RealTime-OSを利用したリアルタイム平衡計算コードを用いてプラズマ位置形状の同定を行っている。その仕様は、ポロイダル断面R1.5m以下,z-1.2m以上1.2m以下の範囲内を各々50mmピッチとする30 times 48のメッシュ粗さの時に、2msec以内で１回の計算を行うものである。一方、制御という観点でいえば、QUEST装置における渦電流効果の時定数が数ミリ秒であり、1回の計算に要する時間は、これより充分短いことが望ましい。そこで本研究では、この数値計算をFPGA (Field-Programmable Gate Array)上で行い、リアルタイム平衡計算コードの更なる高速化を目指す。

双方向プレゼンス投影と制御室視野を考慮した高い臨場感をもつ遠隔実験参加システムの研究/ 　従来から遠隔実験に用いられてきたビデオ会議システムや監視カメラは、注意の対象である相手（人・物）を写すという要素が強く、制御室風景の投影＝臨場感の演出、には必ずしもそぐわなかった。本研究では、注意の主対象である実験データアクセス画面の後面、「デスクトップ背景」に実験室風景をリアルタイム投影すると共に、そのスクリーンサイズを人間の有効視野角に最適化することで、視覚的ストレスなく実験風景に没入できるコンパクトな遠隔実験参加システムのアイデアを提案している。これは従来にない新たな技法となる。 　本研究の成果は、国内外の遠隔共同実験が求める「高い臨場感」を実現し、GAMMA10、LHD、QUEST のみならず、ITER 等の遠隔実験システムにも大きく貢献すると期待される。
