Allowable aperture size of the front end for the high-heat-load undulator beamlines of SPring-8.
A systematic study to determinine the allowable aperture size of the front end for the SPring-8 high-heat-load undulator beamlines has been performed, from the viewpoint of protecting the front-end Be window from thermomechanical failure, and based on the results of ANSYS finite-element analyses. These results have revealed that the allowable aperture size of the front end ranges approximately from 1.06 mm(2) to 3.2 mm(2) depending on the K-parameter and the filter thickness.
