Superlow density experiment on HT-6M tokamak
Description
The HT-6M tokamak can be operated stably in the superlow density region with a few overhot electrons, by some specific methods. The main parameters are N-bare=(0.2-0.6)x1013cm-3, Ip=60-80 kA, Vl=0.7-2.0 V, B=7-10 kG, a=18 cm R=63 cm. In these discharges, the plasma density was determined entirely by limiter and wall outgassing; it was totally independent of the initial hydrogen pressure, P0. The plasma was quiescent, with very small sawteeth. MHD instabilities (m=2,3) only appeared in the current decay stage. The plasma had a peaked Te(r) and a flat Ne(r) profile. The energy confinement time (τe = 1-2 ms) was about two to four times the value calculated from the Alcator scaling law. (author). 3 refs, 6 figs
