【摘要】 在"闪光二号"脉冲电子束加速器上,采用微型红外通光传感技术和直接测量特定时间间隔的探头原理,对一种多孔疏松结构材料的电子束辐射冲量耦合特性进行了实验研究。实验表明:当电子束的平均能量为0.551 MeV,能注量为257±34 J/cm2时,多孔疏松结构材料的冲量耦合系数为1.73±0.26 Pa.s/(J.cm-2).更多还原

【Abstract】 The coupling characteristics of blow-off impulse in a kind of porous distended material radiated by pulsed electron beam were studied experimentally by the probe principles of directly measuring the specific time intervals and sensor technique of infrared ray on"FLASHⅡ"electron accelerator.The experimented results show that,under the radiation of electron beam with energy flux F of 257±34 J/cm2 and average energy Eav of 0.551 MeV,the coupling coefficient of blow-off impulse of the porous distended material is 1.73±0.26 Pa·s/(J·cm-2).更多还原
