Water adsorption±desorption on aluminum surface

Water adsorption±desorption on aluminum surface studied at the Synchrotron Radiation Research Center (SRRC) is described. Both the thermal desorption and the photon stimulated desorption were studied. It was observed that the outgassing behavior of water is quite different from that of the other gases. Experimental results showed that the processes of venting, evacuation and vacuum treatment are sensitive to the water desorption behavior. # 2001 Elsevier Science B.V. All rights reserved.
