WALL CONDITIONING OF THE JIPP T-II TORUS BY AC DISCHARGE CLEANING

概要
- 論文の詳細を見る
Optimization of discharge cleaning was studied by using 60Hz AC and cw ECR discharges. Reduction rate of oxygen was investigated for variations of the wall temperature. It has been confirmed that, below 300℃, the reduction rate increases as the wall temperature is raised. A simple model is proposed for the cleaning process and H_2O pressure is calculated as a function of plasma density on the basis of this model. By comparing the calcurated results to an experimental observation, it has been found that it is essential to raise the electron density of the discharge-cleaning plasma high enough that the dissociation-loss rate of H_2O is as large as the sticking-loss rate in order to optimize the cleaning.
