Photon stimulated desorption of neutral species (PSD) is the major dynamic gas load in electron synchrotron light source. In the National Synchrotron Light Source, (NSLS) PSD presented initial machine commissioning difficulty. Sensitivity to surface contamination on PSD has been experienced during an incident of Fomblin Oil contamination.{sup 1} U10B-photon stimulated desorption experimental station is constructed to investigate: 1---the degree of the contribution to the photon stimulated desorption (PSD) from primary photon flux and scattered secondary photon flux, 2---the underlying mechanism for photon stimulated desorption, 3---criteria to chose the proper beam tube material for future accelerators such as SXLS, FEL, superconducting super collider (SSC), ALS... . In this report, only photon stimulated desorption of neutral species (PSD) from stainless steel and aluminum is reported.
