Operation of most tokamaks in limited byqa, the edge safety factor, which is usually about 2–3. In the SINP tokamak we have been able to obtain discharges withqa 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 lowqa discharges.
