Bombardment of a sample surface with a primary ion beam followed by mass
spectrometry of the emitted secondary ions constitutes secondary ion mass
spectrometry (SIMS).
The best SIMS reference is Secondary Ion Mass Spectrometry: Basic
Concepts, Instrumental Aspects, Applications, and Trends, by A. Benninghoven,
F. G. Rüdenauer, and H. W. Werner, Wiley, New York, 1987 (1227 pages).
