本文介绍了E型电子枪加装测速装置的原理,讨论了实验中所能遇到的各种问题。实验表明该装置的探测极板寿命,可以达到石英振荡器极板寿命的一百倍到一千倍, 测速的重复性优于5％。
This paper introduces the principle of E-gun with speed-measuring device and discusses various problems that can be encountered in the experiment. Experiments show that the probe plate life of the device can reach the quartz oscillator plate life of one hundred times to a thousand times, speed repeatability better than 5%.
