Abstract

A graphite foil heat absorber protecting a beryllium window from thermomechanical damage was overheated, sublimated, and became partially transparent by multipole wiggler radiation. A simple theoretical model on heating of the foil-type filter by multipole wiggler radiation was presented, confirmed experimentally, and applied to analyze the failure.
