Abstract
The IsoTrace (Isotope and Rare Atom Counting Equipment) facility is based on a small tandem electrostatic accelerator (General Ionex Corporation 3 MV Tandetron). When fully commissioned the laboratory will offer a wide range of analytical strategies for SIMS at higher energy. Three ion sources are currently being tested. Two of these employ wide ( 0.25–1.0 mm), high current (tens of μA) beams of Cs+ or I- for ultrasensitive (sub-ppb) analysis of bulk samples and the third, when adapted to sputtering mode in 1984, will be part of an ion microprobe attachment for ppm-ppb trace element and isotopic work.KeywordsAccelerator Mass SpectrometryAccelerator Mass SpectrometryElectric AnalyserMolecular FragmentationMicroprobe SystemThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
