摘要
采用高Z杂质注入HL1M等离子体中,触发等离子体电流衰竭的实验已经施行.用激光吹气注入高Z杂质能够增加辐射冷却,等离子体在-3ms时间内迅速冷却而且在电流终止之前电子温度损失约80%.实验证明它是一种使得大型聚变实验装置上在放电破裂之前显著减少等离子体中热能而且安全终止放电的简单、快速和有效的途径.
A preliminary experiment for triggering a Plasma current quench by means of injection of high-Z impurities has been performed on the HL-1M before the major disruption. Using injection of impurity with higher charge of the nuclei allows us to increase the radiation cooling on a 3 ms time scale and the electronic temperature loss contract is 80% before current terminates. It can be a simple and potential approach to decrease significantly the plasma thermal energy and the magnetic field energy before a disruption and to a safe plasma termination.
