Abstract: In the laboratory study of extreme conditions of temperature and density, the expo22sure of matter to high intensity radiation sources has been of central importance. Here23 we interrogate the performance of multi-layered targets in experiments involving high24 intensity, hard x-ray irradiation, motivated by the advent of extremely high bright25ness hard x-ray sources, such as free electron lasers and 4th-generation synchrotron26 facilities. Intense hard x-ray beams can deliver signicant energy in targets having27 thick x-ray transparent layers (tampers) around samples of interest, for the study28 of novel states of matter and materials' dynamics. Heated-state lifetimes in such29 targets can approach the microsecond level, regardless of radiation pulse duration,30 enabling the exploration of conditions of local thermal and thermodynamic equilib31rium at extreme temperature in solid density matter. The thermal and mechanical32 response of such thick layered targets following x-ray heating, including hydrody33namic relaxation and heat ow on picosecond to millisecond timescales, is modeled34 using radiation hydrocode simulation, nite element analysis, and thermodynamic35 calculations. Assessing the potential for target survival over one or more exposures,36 and resistance to damage arising from heating and resulting mechanical stresses, this37 study doubles as an investigation into the performance of diamond-anvil high pres38sure cells under high x-ray uences. Long used in conjunction with synchrotron x-ray39 radiation and high power optical lasers, the strong connement aorded by such cells40 suggests novel applications at emerging high intensity x-ray facilities and new routes41 to studying thermodynamic equilibrium states of warm, very dense matter.
