Predictions of electron cyclotron current drive efficiency for a top-launched extraordinary mode in a Tokamak

R O Dendy, R W Harvey, M R OBrien1987年Plasma Physics and Controlled FusionIF 2.2出版社

A relativistic ray tracing code is used in conjunction with a Fokker-Planck code to calculate the dependence of current drive efficiency on plasma parameters and wave characteristics for top launch. Physical considerations include the interplay of wave polarisation, relativistic cyclotron resonance, optical path length, and electron collisionality. The current drive efficiency at a given temperature is a function of only two parameters: electron number density, and the parameter beta identical to ( omega - Omega 0)/k/sub /// nu B, which includes information on magnetic field strength, wave launch angle and plasma temperature. Peak current drive efficiencies can exceed by 25% the values for comparable inside launch configurations.

相対論的レイトレーシングコードをフォッカー=プランクコードと併用し、トップ打ち込みに対する電流駆動効率のプラズマパラメータおよび波動特性への依存性を計算する。物理的考察には、波動の偏極、相対論的サイクロトロン共鳴、光路長、および電子衝突性の相互作用が含まれる。所与の温度における電流駆動効率は、電子数密度と、β≡(ω-Ω₀)/k‖v‖という2つのパラメータのみの関数である。ここでβは磁場、波動の打ち込み角度、およびプラズマ温度に関する情報を含む。ピーク電流駆動効率は、同等のインサイド打ち込み配置における値よりも25%超となり得る。
