Plasma Parameters Measurement in IR-T1 Tokamak with Langmuir Probe and the Simulation of the Lower Hybrid Waves in IR-T1, JET and NSTX Tokamaks

摘要

Ohmic heating is not enough for ignition mode in plasma and fusion reactions. Therefore additional methods, has been used, such as wave injection into plasma. Radio frequency wave injection into fusion plasma is more considered. Interaction between waves and plasma is described by Fokker-Planck equation with an added quasi-linear term. This paper is composed of three sections. At first, required experimental parameters for LSC program such as temperature and density measured by a Movable Langmuir Probe in IR-T1, and then we presented Computational solution of Fokker-Planck equation with Adjoint method and Rosenbluth potentials to achieve distribution function in velocity space and at least, we simulated Lower Hybrid Waves and quasi-linear term for NSTX, JET and IR-T1 tokamak. The results of this simulation showed higher efficiency of NSTX, in comparison with JET and IR-T1.
