Improvements in a Calorimeter for High-Power CW Lasers

March 1, 1978
Author(s)
G. E. Chamberlain, Philip A. Simpson, R L. Smith
Measurement certainty with the BB series of electrically calibrated calorimeters for high-energy lasers has been enhanced by the addition of monitors for energy backscattered from the meter and for energy missing the entrance aperture (overspill). The

Surface Analysis by Electron Spectroscopy at High Pressures

March 1, 1978
Author(s)
Cedric Powell
Surface analyses are now made by techniques such as Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS), and appearance potential spectroscopy (APS). These techniques utilize low-energy electrons and have high surface sensitivity but

Auger Electron Spectroscopy

Cedric J. Powell
A convenient measure of surface sensitivity in Auger-electron spectroscopy (AES) and x-ray photoelectron spectroscopy (XPS) is the mean escape depth (MED). If the effects of elastic-electron scattering are neglected, the MED is equal to the electron

High Resolution Photoemission Study of Condensed Layers of Nitrogen and Carbon Monoxide

February 1, 1978
Author(s)
P R. Norton, R L. Tapping, H P. Broida, John William Gadzuk, B Waclawski
Values are reported for the absolute yields of KVV Auger electrons from beryllium and L 23VV Auger electrons from aluminum excited by 60- to 220-keV proton bombardment. The measurements were made using semi-infinite evaporated samples, and the results were
