Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Simultaneous auger electron spectroscopy and ion sputtering have been used to measure the sputter yield, S (atom/ion), for Ar+ on carbon, tungsten, niobium, and silver in the energy range from 0.5 to 1.5 keV and for H+ on tungsten, carbon, and silver at 11 keV. All measurements were performed on thin films, ranging in thickness from 150 to 6000 Å, which were maintained at room temperature during bombardment. These films were produced by vacuum vapor deposition, and the thicknesses were measured by surface profilometry. The auger electron signals were used to determine the time required to etch through a film; from these measurements and a knowledge of the ion current density, the sputter yield was determined. For Ar+, 0.7 ≲ S ≲ 5.1 and for H+, 0.004 ≲ S ≲ 0.04 for the various materials studied in this energy range. Agreement with earlier experimental results is generally within ±25%.
