Preliminary investigation of changes in x-ray multilayer optics subjected to high radiation flux

SummaryWe have outlined our on-going project to investigate the heat loading effects on metalmultilayers irradiated by extreme fluxes from high temperature plasmas. The desired experimental results have been obtained and modeling is under way.AcknowledgmentsWe wish to thank the PROTO II experimental team and machine crew, and EG&G for their assistance. This work was supported by the Department of Energy.References1. R. H. Day and T. W.
