C. Benvenuti et al., A SCANNING AUGER-ELECTRON SPECTROMETER FOR INTERNAL SURFACE-ANALYSIS OF LARGE ELECTRON-POSITRON-2 SUPERCONDUCTING RADIOFREQUENCY CAVITIES, Review of scientific instruments, 67(8), 1996, pp. 2788-2795
A computer-controlled surface analysis instrument, incorporating stati
c Auger electron spectroscopy, scanning Auger mapping, and secondary e
lectron imaging, has been designed and built at CERN to study and char
acterize the inner surface of superconducting radio-frequency cavities
to be installed in the Large Electron Positron collider. A detailed d
escription of the instrument, including the analytical head, the contr
ol system, and the vacuum system is presented. Some recent results obt
ained from the cavities provide examples of the instrument's capabilit
ies. (C) 1996 American Institute of Physics.
