WebbThe abbreviation TOF-SIMS is an acronym for the combination of secondary ion mass spectrometry (SIMS) with a time-of-flight (TOF) mass analyser. The sample to be analysed is bombarded with a primary ion beam with a kinetic energy of a few keV. The ions collide with the surface, releasing their energy and generating a shock cascade. http://simslab.rice.edu/surface-analysis-lab/teaching-activities-resources/time-of-flight-secondary-ion-mass-spectrometry/ green light on porch meaning
