用二级吸附泵作前置真空泵的无油真空机组,为要获得10~(-4)乇的前置真空,需要在被抽容器压强降到1乇左右时关闭第一级吸附泵的阀门。用热偶计或皮氏计测量这个压强速度慢、读数不准,因此提出试制高压强电离计的任务。工农兵学员,在教研组工人师傅和教师的支持和帮助下,一面建立校准系统,设计高压强电离计管的结构,一面试制氧化钇阴极和制作电源,在不到半年的时间内,做出了一些初步结果。
In order to obtain a pre-vacuum of 10 -4 Torr, an oil-less vacuum unit with a two-stage adsorption pump as a pre-vacuum pump is required to close the first-stage adsorption pump valve when the pressure in the vessel is reduced to about 1 Torr . Thermocouple or Pei’s meter to measure the speed of this pressure is slow, the reading is not allowed, so the proposed high-pressure ionization test mission. With the support and assistance of teachers and teachers of the teaching and research team, the workers, peasants and soldiers were able to set up a calibration system, design the structure of the high-pressure ionization tube, try out the yttrium oxide cathode and make a power supply in less than half a year Some preliminary results.
