| Abstract: | A preliminary experiment triggering a plasma current quench by laser ablation ofhigh-Z impurities has been performed in the HL-1M tokamak. The injection ofimpurities with higher electric charges into tokamak plasmas can increase theradiation cooling of the plasma. Resistive, highly radiating plasma formed prior tothe thermal quench can dissipate both the thermal and magnetic energies, which ispossibly a simple and potential approach to reducing significantly the plasmathermal energy and magnetic energy before a disruption thereby a safe plasmatermination is obtained. |
