| 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. |
