Abstract
Operation of most tokamaks in limited byq a, the edge safety factor, which is usually about 2–3. In the SINP tokamak we have been able to obtain discharges withq a values as low as 0·8. In this paper we describe our results on the setting up processes and the MHD activity associated with these ultra lowq a discharges.
