摘要

主要介绍了利用高功率离子束模拟1keV黑体辐射X射线对材料的热-力学效应（thermal-mechanicaleffects）的初步研究结果。计算了“闪光二号”加速器产生的高功率离子束（质子束）和1keV黑体辐射X射线在材料中的能量沉积剖面

计算结果表明二者的能量沉积范围和剖面变化趋势基本一致。给出了利用“闪光二号”加速器高功率离子束辐照不同材料样品的初步实验结果。所辐照的样品表面镀层被剥离掉

Cu和Al样品表面有明显的熔融痕迹

样品的质量损失约几十毫克

3mm厚的石墨样品碎裂成数块

1mm厚的Al靶形变达到6mm。实测的5mm厚硬Al靶背面应力波峰值约35MPa。因而可以利用“闪光二号”加速器产生的高功率离子束模拟1keV黑体辐射X射线的热-力学效应。

Abstract

Preliminary research results for thermal-mechanical effects of the materials irradiated by high power pulsed ion beams (HPIBs) applied to simulate 1 keV black radiation X-rays are reported. The energy deposition profiles in Al samples for 1 keV black radiation and HPIB from FLASH II accelerator were calculated. Their energy deposition range and variation trend of the profile were essentially similar. The experimental results for the samples irradiated by HPIB from FLASH II accelerator are also presented. After the HPIB irradiation

the chrome plated on the metal surface was stripped by HPIB; the evaporating and melting traces on the surface of Al and Cu samples were visible; the sample’s mass loss was about 30—100 mg; the graphite samples were shattered and the deformation of thin Al samples was about 6 mm. The stress wave of LY12 Al samples irradiated by HPIB was also measured

which attained 35 MPa. It is suggested that HPIB can be used for simulating thermal-mechanical effects of materials irradiated by 1 keV black radiation X rays.
