WebSynchrotron radiation at the Synchrotron Ultraviolet Radiation Facility at the National Bureau of Standards has been employed to study the adsorption of oxygen on a Ti(001) surface using photon-stimulated desorption (PSD), electron-stimulated desorption (ESD), and ultraviolet photoemission spectroscopy (UPS). The dominant ESD and PSD products … WebMay 15, 1984 · Photon stimulated desorption (PSD) refers to the ejection of ions, atoms, or molecular fragments from a surface initiated by the adsorption of single photons; to date, most studies have concentrated on the detection of ions. The properties of PSD which make it attractive as a surface characterization tool are its extreme surface sensitivity ...

WebNEG coating can reduce drastically the Photon Stimulated Desorption (PSD) effect [3], hence the conditioning time. At SOLEIL, in addition to the standard pumps, the use of NEG coating has been implemented in an extensive way to all the aluminium straight vacuum vessels of the storage ring that means quadrupole/sextupole type and WebPhoton stimulated ion desorption (PSID) surface EXAFS (SEXAFS) showed early promi se, bei ng successfully appl i ed to the Mo (100) /0 system [1].
