A tomographic reconstruction system with five channels for visible light emission has been developed and applied to observe the visible light emission from HYBTOK-II tokamak plasma. A compact and low cost computed tomography (CT) system with a good spatial and time resolution was established using an array of charge coupled devices. The shuttering capability of the CT system is 300 μs. A rapid change of the emission profile due to the deviation from the tokamak equilibrium was successfully followed. Present CT system with five CCD cameras enables us to recognize a local increment of the visible light emission due to the plasma arcing, which is difficult to observe with the conventional three camera CT system, which is often employed for fusion plasma diagnostics.

Gaseous Silicon Plasma Generated by a Low-Temperature Tokamak Discharge 査読有り

平松健司, 高村秀一, 大野哲靖

プラズマ・核融合学会誌 69 巻 ( 2 ) 頁： p121 - 128 1993年2月

担当区分：最終著者記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：プラズマ・核融合学会

Gaseous silicon plasma is generated in a hydrogen gas environment by use of a plasmaassisted Si arc in a tokamak discharge with a low electronic temperature (≦10eV) , a high electron density (～ 10^<12>cm^<-3>) , and a low hydrogen gas pressure (～10^<-5> Torr) . On arcing, the spectral lines of Si II, Si III and Si IV ions as well as Si H radicals have been observed. Using the comparison spectroscopic method with no need of absolute measurement of line intensity, doubly ionized silicon ions are observed to be dominant, and the ionic density is estimated to be 10^<11>～10^<12>cm^<-3>. The slllcon hydrogen plasma thus produced Is useful and has a potential for plasma processing, such as a-Si:H synthesis.
