Modelling of discharge dynamics in tokamaks
Abstract
Results are presented for the modeling of discharge development in tokamaks. A detailed study is performed of the initial phase (ionization and current rise), the influence of MHD processes and impurity radiation in the T-10 tokamak. The energy balance in the T-11 tokamak with neutral-beam injection is examined. An analysis is made of the processes of beam particle ionization, hot-ion trapping and energy transfer to the plasma. The possibility of obtaining the conditions for low collision frequency is also discussed.
