The temperat re and thermal stress distrib tions in the front end photo sh tter of Shanghai Synchrotron Radiation Facility ( SSRF) w ere sim lated caref lly by the finite element package A NSYS. Analysis res lts reveal that maxim m thermal stress of the new photo sh tter is remarkably red ced and enhances the photo sh tters end rance for high synchrotron radiation thermal load, th s f lfilling the design req irement of the SSRF front end.
