摘要

摘要获得了一个可以描述电子分布函数演变和螺旋子产生非感应电流的准线性方程。研究表明，在分析的情况下，福克-普朗克方程可以用纵向电子速度空间中的一元方程来近似，其扩散系数与电子由于朗道阻尼而吸收的螺旋子功率成正比。

A 1D Quasilinear Equation Describing the Current Drive Excitation by Helicons in a Tokamak Plasma

Abstract—

A quasilinear equation which allows describing evolution of the electron distribution function and generation of non-inductive currents by helicons is obtained. It is shown that in the analyzed case the Fokker–Planck equation can be approximated by a one-dimensional equation in the longitudinal electron velocity space with a diffusion coefficient proportional to the helicon power absorbed by electrons due to Landau damping.

期刊介绍： Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
