摘要: 在强光一号脉冲加速器上进行了国内首次的实验室软X光辐射三种材料的喷射冲量研究。结果表明，在能量为(0.2～0.33)keV、平均脉宽为39ns左右的X光辐射下，对灰漆、白漆和硬铝，在能注量分别为(92～152)J/cm2、(115～136)J/cm2和(163～192)J/cm2时，它们的冲量耦合系数分别为(0.61～0.80)Pa·s/(J·cm-2)、(0.58～0.97)Pa·s/(J·cm-2)和(0.61～0.84)Pa·s/(J·cm-2)。Abstract: The blowoff impulse of three different materials irradiated by soft Xray was studied on QiangguangI pulsed accelerator. The experimental results show that the coupling coefficients of blowoff impulse for grey paint, white paint and aluminum alloy irradiaded by Xray, the enegy of which was in the range from 0.20keV to 0.33keV and the average pulse width of which was 39ns, were in the range from 0.61Pa.s/(J·cm-2) to 0.80 Pa·s/(J·cm-2), from 0.58 Pa·s/(J·cm-2) to 0.97 Pa·s/(J·cm-2) and from 0.61 Pa·s/(J·cm-2) to 0.84 Pa·s/(J·cm-2), respectively, when Xray energy flux was in the range from 92J/cm2 to 136J/cm2, from 115J/cm2 to 159J/cm2 and from 163J/cm2 to 192J/cm2, respeclively.
