Experimental Studies of Blowoff Impulse Induced by Electron Beam with Different Materials and Different Energy Fluxes

摘要: 介绍了采用直接测量特定时间间隔系列和微型红外通光式传感技术的探头原理，在闪光二号电子束装置上进行的喷射冲量随不同材料和不同能通量而变化的实验研究。实验结果表明，在能通量大体相同时，A和B这两种特种材料的喷射冲量耦合系数分别只有LY-12铝的1/3和1/2左右。这说明此两种特种材料在受辐照条件下具有良好的降低喷射冲量的性能。

Abstract: In this paper, the experimental studies of variation of blowoff impulse with different materials and different energy fluxes are described. The experiments are conducted on FLASH-Ⅱ electron beam equipment with the probe principle of directly measuring the specific series of time intervals and miniature transduction technique passing infrared ray. The experimental results show that the coupling coefficients of blowoff impulse for two specific materials only is 1/3 and 1/2 or so of those of LY-12 aluminum alloy, respectively, in about the same energy fluxes. This shows that the two specific materials when they are radiated possess good property which can reduce blowoff impulses.
