摘要
HL-1M是HL-1的改进装置,去掉铜壳后,对极向场线圈和电源都做了必要的修改。此外,还增加了四个快垂直场线圈,并采用可控环流四象限晶闸管交流器供电。对装置调试和运行结果表明.反馈控制系统能很好地维持等离子体平衡。放电一直持续到铁芯变压器的伏秒数用完为止,最长达1040ms。在多数放电的平顶段,等离子体位置都被控制在±4mm之内.
The HL-1M is a modification of the HL-1 tokamak. The poloidal field coils and the power supply have been modified after the removal of the copper shell. Besides. four fast vertical field coils have been added, supplied by a four-quadrant thyristor convertor, with the circulating current controlled. The commissioning results and subsequent operation showed that the plasma position was well maintained by the feedback control system with discharge continued until the exhaustion of the volt-seconds of the iron core transformer.The maximum discharge time is 1040ms, and the horizontal and vertical plasma positions can be kept within ±4mm over the plateau of the plasma current.
