一、概述 用于晶体光阀管中的DKDP电光晶体,由于它处于真空环境并依靠电子束的轰击而工作,所以它的真空性能以及抗电子束轰击的能力对电光晶体本身是否能正常工作显得十分重要。 晶体光阀管真空性能的研究,国外早有报导,但它们只研究了电子束轰击下以及不同温度下光阀管内气体总压强的变化,没有进一步分析气氛变化的过程和气体的种类。这对保证DKDP电 I. Overview DKDP electro-optic crystal used in crystal light valve tube, because it is in a vacuum environment and rely on the bombardment of the electron beam to work, so its vacuum performance and the ability of anti-electron beam bombardment of the electro-optic crystal itself is working properly Very important. However, they only studied the change of the total pressure of the gas in the valve tube under the electron beam bombardment and at different temperatures. There is no further analysis of the process of changing the atmosphere and the type of gas. This pair guarantees DKDP electricity
