High Power ICRF Heating Experiments on the JIPP T-IIU Tokamak

概要
- 論文の詳細を見る
In the JIPP T-IIU tokamak, a high power ICRF heating experiment has been conducted up to an extremely high power density (∿2MW/m^3) with a total rf power of P_rf=2MW. Much attention has been paid initially to the problem of impurities, and it has been found that a) the adoption of low-Z materials for the limiter, b) in situ carbon coating (i. e., carbonization) and c) adequate gas-puffing synchronized to the rf pulse are very effective in suppressing radiation loss. In combination with these methods, a remarkable reduction in metal impurities (especially in iron impurity) has been achieved, suppressing the total radiation loss to less than 30∿40% of the input power. In these reduced-radiation-loss plasmas, characteristics of ICRF-heated plasmas have been intensively studied. With an increase in the ICRF heating power, the deterioration of the energy confinement time has been observed, indicating quantitative agreement with Kaye-Goldston L-mode scaling. It is shown that the so-called profile consistency, which is the leading feature in NBI-heated plasmas, holds also in the ICRF-heated plasma. It has been observed that the electron temperature profile responds only to the safety factor q(a), and is not changed by the deposition profile controlled by tailoring the K_H-spectrum.
