The Pollution on the Surface of Ceramics Vacuum Envelope when Mo Ions are Oxidized 钼离子的氧化对电真空陶瓷管壳的污染
How the high precision and high strength of the envelope main lens are properly achieved by means of vacuum precision envelope forming technique. Test results are presented. 玻壳真空精密成形工艺如何较好地实现了玻壳主透镜的高精度和高强度、最后给出了测试结果。
It was the difference of the influence of the cathode plasma generated in the process of emitting beams on the vacuum diode and the recovery velocity of the cathode plasma that resulted in the different envelope radii of the two beams. 实验得到的两个脉冲电子束包络半径不完全一致,这是由于天鹅绒阴极在发射电子束过程中产生的阴极等离子体对真空二极管的影响程度不同所导致的。
