Abstract
Two interesting features of runaway behaviour are observed in the star tup phase of the very low q(a) (VLQ) (1 < q(a) < 2) discharges in the SINP tokamak. As q(a) was reduced by lowering the toroidal field value s, the hard X (HX) ray intensity (which indicates the presence of runa way electrons) fell considerably. The time at which the peak in the HX ray intensity occurs also shifts ahead in time, indicating premature dumping of the runaway electrons. This seems to aid the development of the rest of the discharge as exhibited by the diamagnetic loop signal .
