    • Abstract

       

      The behaviour of runaway electrons in the SINP tokamak, which can be operated in a normal edge safety factor ($q_{a}$) (NQ) discharge configuration as well as in a low $q_{a}$ (LQ) configuration, was experimentally investigated, during the initial plasma generation phase. An energy analysis of the runaway electron dynamics in the rise phase of the SINP tokamak discharges was also made. A comparison of the runaway electron diffusion coefficients in NQ and LQ is carried out in this paper.
