Suppression of runaway current by electrode biasing and limiter biasing on J-TEXT
文献摘要：
The avoidance of runaway electrons(REs)generated during plasma disruption is of great concern for the safe operation of tokamak devices.Experimental study on the suppression of runaway current by electrode biasing(EB)and limiter biasing(LB)has been performed on the J-TEXT tokamak,which could be an alternative way to suppress the runaway current.The experimental results show that the higher the voltage value,the smaller the runaway current in both EB and LB experiments.The runaway current can be completely suppressed at an electrode biased voltage of+450 V and a limiter biased voltage of+300 V.The comparison of the energy spectra during the runaway plateau phase shows that the maximum energy max(ERE)and radiation temperature THXR of hard x-rays(HXRs)are significantly reduced after the application of+200 V limiter biased voltage.The electric field generated by the biased voltage may be the key factor to suppress the runaway current,and the measured radial electric field increases obviously after the voltage is applied.This may result in an increase in the loss of REs to realize the suppression of runaway current.
