The high power and high density of synchrotron radiation irradiates the crotch absorber inducing not only the thermal deformation but also the photon-stimulated desorption 27 1 (21) (PSD) phenomena. For making sure of the quality of crotch absorber, the PSD of crotch absorber was studied by using synchrotron radiation at TLS BL19B. The experimental vacuum chamber need to cal
