【摘要】 新建成的HL1M装置离子回旋共振加热(ICRH)射频系统,经工程联调,已达到输出功率500kW、脉宽100ms、频率26～36MHz。在环向场BT=2T、等离子体电流Ip=150kA、电子密度ne=(1～5)×1013cm-3条件下,首次对HL1M装置以氢为少数粒子的氘等离子体进行了离子回旋共振加热实验,使电子温度上升了20%,并观测到了典型的杂质行为和边缘等离子体参数的改变更多还原

【Abstract】 The ICRH system has been recently constructed on the HL 1 M tokamak,and is operated with RF power of50 0 k W at frequency of2 6～ 3 6MHz and pulse duration of1 2 0 ms. The initial ICRH heating experimentsare performed atthe parametersof Ip=1 50 k A,BT=2 T, ne=(1～ 5)× 1 0 1 3cm- 3and f =3 0 MHz,using a deuterium plasma with 5% ofhydrogen mi nority ions.Changes of impurities and edge plasma parameters are observed and a2 0 % incre mentofelectron temperature is obtained.更多还原
