低温技术在受控核聚变实验中的应用

在中国环流器一号（ＨＬ－１）等离子体物理实验中，增加了弹丸注入和电子回旋共振加热系统。对低温技术在其中的应用情况，液氦输送系统，输液方法及氦气回收系统做了介绍。在一次等离子体物理实验中，总共使用液氦２７３３Ｌ。在弹丸注入系统中，使装置的等离子体密度提高了１～２倍。在装置上成功地实现了电子回旋共振加热，使等离子体电子温度增加３０％以上。

Application of Cryogenic Techology in Controlled Thermo nuclear Fusion Experiments

The pellet injection and the electron cyclotron resonance heating system have been involved in the China Torus Current Device No. 1(HL-1)As to the applications cryogenic tcchnology the liguid heluim transmissionsystem,the liguid heluim transmission method and the heluim recovery areintroduced in the present paper. The quantity of liquid heluim used in aplusma physics experiment was amounted to 2733 liters.The first shot wasejected successfully from a pellet injection system,which made the plasmadensity in the device increase by 2 or 3 lirnes.The electron cyclotron reso-nance heting was realized successfully in the device,which made the pla-sma electron temperature increase by a factor of 30%.
