Abstract

The photon shutters (PS) on the insertion device front end of the beamlines at the Advanced Photon Source (APS) are designed to fully intercept powerful 7-GeV undulator radiation. Traditional materials (oxygen-free copper and Glidcop) are used in their construction. The heat flux from the undulators is enormous. For example, in the later phase of the project, the first photon shutter (PS1) placed at a distance of 17 m from the Undulator A source is subjected to 1400 W/mm² at normal incidence with a total power of 11.4 kW. Our analysis of PS1 indicates that the face plate made of either graphite or beryllium retains its integrity in most of the cases. The maximum effective stress of the absorber plate (made of annealed OFHC) exceeds the yield strength (50 MPa) except in the case of an absorber with a 10-mm graphite face plate.
