摘要：

Beryllium windows were tested as the first target in a project for experimental simulations of heat load effects on beamline optical elements under direct irradiation of undulator and wiggler radiation. Maximum temperature at the window center, vertical temperature distribution, and cooling capability by thermal conduction were studied. It turned out that thermomechanical failure occurred when the temperature difference between the window center and its peripheral edges exceeded about 200-degrees-C. This fact was in good agreement with a simple maximum-shearing-stress theory of the failure condition.
