A current generation by Thomson scattering in a plasma with velocity shear and temperature gradient

S Hinata, K Daneshvar1984年Plasma Physics and Controlled FusionIF 2.2出版社

Since the photons transfer momentum much more efficiently to electrons through Thomson scattering, selective acceleration of electrons will take place in an anisotropic radiation field, thus contributing to an electric current generation. The authors consider an optically thick, fully ionized, hydrogen plasma with the temperature gradient (dT/dZ) and the velocity shear (dVx/dZ) in a slab geometry (no spatial dependence in x- and y-directions). They calculate the current generation rate in the direction of the plasma flow velocity (x-direction) as the function of dT/dZ and dVx/dZ.

光子はトムソン散乱を通じて電子に運動量をはるかに効率的に伝達するため、異方性放射場では電子の選択的加速が生じ、それによって電流生成に寄与することになる。著者らは、スラブ幾何学(x方向およびy方向に依存性がない)において、温度勾配(dT/dZ)と速度シア(dVx/dZ)を有する光学的に厚い完全電離水素プラズマを考察する。彼らは、プラズマ流速度の方向(x方向)における電流生成率を、dT/dZおよびdVx/dZの関数として計算する。
