Alpha particle classical transport in tokamaks

Shaojie Wang, Lijian Qiu1996年被引用 1Nuclear FusionIF 3出版社

Alpha particle classical transport for both axisymmetric and nonaxisymmetric cases is comprehensively considered. A two dimensional (one dimension for configuration space and one dimension for velocity space) time-dependent linear Fokker Planck equation is computed to evaluate the steady state alpha particle loss fraction and the heating efficiency. The calculation results show that: the effect of ripple on the global particle confinement time is more apparent than its effect on the heating efficiency; the ripple has little effect on the alpha particle heating profile; the larger the ripple amplitude is, the harder the lost alpha particle energy spectrum is

アルファ粒子の古典輸送を、軸対称の場合と非軸対称の場合の両方について包括的に考察する。二次元(配置空間に一次元、速度空間に一次元)の時間依存線形フォッカー・プランク方程式を計算し、定常状態のアルファ粒子損失割合と加熱効率を評価する。計算結果は以下のことを示す:リップルが全体の閉じ込め時間に及ぼす影響は、加熱効率に及ぼす影響よりも顕著である;リップルはアルファ粒子の加熱プロファイルにはほとんど影響を与えない;リップル振幅が大きいほど、失われるアルファ粒子のエネルギースペクトルはより硬くなる。
