A zero-dimentional model to study plasma heating efficiency and thermal insulation at the globus-m tokamak in ohmic heated regimes

Abstract

Experimental study of thermal energy confinement time in magnetic-confinement devices is one of the fundamental problems in plasma physics. This work is devoted to Globus-M data processing technique that incorporates both kinetic and magnetic measurements. Zero dimensional code was developed based on this approach. This simple code allows to calculate important discharge parameters during the experiment (between shots) - electron and ion thermal stored energy content, effective plasma charge and confinement time. Good agreement of 0d calculations and ASTRA modeling indicates that this approach can be applied for routine data processing at Globus-M.
