摘要
本文介绍了小磁镜装置的工作情况。环形钛膜靶受到镜损失粒子轰击而解吸氧，等离子体室的 ＴｉＣ膜受到具有一定能量的 Ｈ°粒子轰击在膜上的氧也解吸。采用微分方程组来描述整个磁镜装置的压强分布，此方程组能定量的计算在等离子体室轻杂质氧的变化。本文也介绍了硬铝合金真空室和圆形双台阶、跑道形单台阶、矩形单台阶法兰的优点，这些台阶法兰都经受了＋１８０℃──－１９５℃的“热冲击”实验，有很好的真空 密封性能。
This paper describes the operation of small mirror machine. Ring Titanium film target is bombed by mirror loss particle, therefore oxygen are desorbed. TiC film is bombed by H ° particle with some energy in the plasma chamber, oxygen on the film are desorbed also. To use the differential equation group describe pressure distribution of the all mirror machine, it can calculate quantitatively the variations of light impurity oxygen in the plasma chamber. The paper also discribes advantages of aludur vacuum chamber and round dualstep flange.track single step flange. rectangular single step flange.These flanges underwent the experiments of “Thermal lash'”at + 180℃-195℃. there are very good property of vacuum sealing.
