本文报道了环六七- 2a（通常称为HL-2A）在电子回旋共振加热（ECRH）放电的平顶阶段和超音速分子束注入（SMBI）存在下大量失控电子的产生[Q]。杨威，核。核聚变47,635(2007)]。在本实验中进行的一组放电，ECRH功率和等离子体电子密度的范围分别为0.8-1.0 MW和（3.0-4.0）×1019 m−3。雪崩效应产生了大量的超热电子[A]。Lazaros、phy。血浆8,1263(2001)]。SMBI引起的回路电压升高导致临界失控能下降，导致大量的超热电子进入失控区。因此，这种现象可能来自于ECRH和SMBI的协同作用。也就是说，ECRH产生的超热电子被加速到失控状态，通过…
In the present paper, it is reported that a large production of runaway electrons has been observed during the flattop phase of electron cyclotron resonance heating (ECRH) discharges and in the presence of supersonic molecular beam injection (SMBI) in the HuanLiuqi-2A (commonly referred to as HL-2A) [Q. W. Yang, Nucl. Fusion 47, S635 (2007)] tokamak. For the set of discharges carried out in the present experiment, the ranges of ECRH power and plasma electron density are 0.8–1.0 MW and (3.0–4.0)×1019 m−3, respectively. A large number of superthermal electrons are produced through the avalanche effect [A. Lazaros, Phys. Plasmas 8, 1263 (2001)] during ECRH. The loop voltage increase due to SMBI gives rise to a decline in the critical runaway energy, which leads to that many superthermal electrons could be converted into runaway region. Therefore, this phenomenon may come from the synergetic effects of ECRH and SMBI. That is, the superthermal electrons created by ECRH are accelerated into runaway regime via t...
