SHRIMP I

The SHRIMP I design consists of a primary column containing the ion source and focusing elements, the source chamber housing the sample, the last of the primary ion optic elements, and the secondary ion extraction optics. The mass analyser consists of a magnetic sector preceded by an electrostatic analyser that compensates for the energy dispersion of the magnet. A quadrupole lens is inserted between the magnet and ESA to minimize second order aberrations. The SHRIMP I design was presented to the first SIMS meeting in Germany but the proceedings volume was never published. The PDF file can be obtained here (Clement.pdf).
