We present preliminary study of the Photon Stimulated Desorption from aluminum vacuum chamber. Synchrotron radiation is generated in electron storage ring when the electron beam pass through magnetic field. In this paper, such synchrotron radiation is simulated on magnetic lattice of the storage beam. The temperature of the vacuum chamber increases due to absorption of photon beam simultaneously the molecular pressure also increases due to desorption of the adsorbed gases. This process of increasing in gases depends upon various physical phenomena, such as irradiation of photon beam due to interaction of electrons in applied magnetic field, secondary emission of electron from surface, heat transfer, and molecular flow of gases. Therefore, the solution of vacuum pressure inside the storage ring depends on various physics. This paper discusses preliminary results of analysis of vacuum pressure combining responsible physics.
