Calculations of the response of inertial fusion energy materials to x-ray and ion irradiation on Z and RHEPP

PDF Version Also Available for Download.

Description

The response of candidate Inertial Fusion Energy first wall materials to the intense bursts of x-rays and ions that will emanate from IFE targets is an important issue for power plants and for any facility that would test high yield target performance. In an effort to gain understanding of the behavior of these materials while undergoing rapid phase changes and to validate code that predict such behaviors, a multi-institution group has been conducting experiments on the 2 and RHEPP facilities at Sandia. As part of this project, calculations of irradiation with tungsten wire array x-ray on 2 and ions on ... continued below

Description

The response of candidate Inertial Fusion Energy first wall materials to the intense bursts of x-rays and ions that will emanate from IFE targets is an important issue for power plants and for any facility that would test high yield target performance. In an effort to gain understanding of the behavior of these materials while undergoing rapid phase changes and to validate code that predict such behaviors, a multi-institution group has been conducting experiments on the 2 and RHEPP facilities at Sandia. As part of this project, calculations of irradiation with tungsten wire array x-ray on 2 and ions on RHEPP have been performed with the BUCKY computer code. When comparing experiments to calculations for graphite and tungsten samples, we have found some behavior that is not predicted by the code. We will show how the greater than 1 keV lines in the 2 tungsten wire array x-ray source affect the material response. On the RHEPP ion experiments, we will show how sensitive the results are to the thermal conductivity of the material.
