プラズマ計測開発 (Development of plasma diagnostics)

境界プラズマ計測

核融合の実現に向けて、プラズマの計測および制御が必要不可欠です。本研究室では静電プローブ計測,レーザーを使ったトムソン散乱計測,分光計測などの手法を用いて特に核融合のプラズマの中でも比較的低温(1000度~10万度程度)のプラズマの計測手法の開発及び詳細な計測を,ダイバータ模擬装置を用いて実施しています。

 

Plasma measurement and control are indispensable to realize nuclear fusion. In our laboratory, we are developing measurement methods for relatively low temperature plasmas (0.1-10 eV) in the boundary region of fusion reactors using electrostatic probing, Thomson scattering using lasers, and spectroscopy, and are performing detailed measurements using a divertor simulator.
