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.

Description
Summary: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 mm2 to 3.2 mm2 depending on the K‐parameter and the filter thickness.
