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)。
The blowoff impulse of three different materials irradiated by soft X-ray was studied on Qiangguang-I pulsed accelerator. The experimental results show that the coupling coefficients of blowoff impulse for grey paint, white paint and aluminum alloy irradiated by X-ray, the energy of which was in the range from 0.20 keV to 0.33 keV and the average pulse width of which was 39 ns, were in the range from 0.61 Pa.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 X-ray energy flux was in the range from 92 J/cm2 to 152 J/cm2, from 115 J/cm2 to 136 J/cm2 and from 163 J/cm2 to 192 J/cm2, respectively.
