Impurity behavior in the high density Aditya Tokamak plasmas

Impurity behaviour has been studied for the high density Aditya Tokamak plasmas. These discharges were operated with increasing toroidal magnetic field and thereby it sustained higher plasma current. Higher densities were achieved with the help of multiple gas puffs. High energy confinement times, sometimes higher than the values predicated by Neo-Alcator scaling for Ohmically heated Tokamak plasma were achieved for these discharges. In this presentation, details studies on visible and VUV emissions will be discussed for its role in these high densities plasma discharges
