Reaction Ion Microscopes (RIMs) are axial-field electrostatic spectrometers extensively used in atomic physics to study few-body reactions. The high resolution and 4π solid angle acceptance achievable with these devices have made them essential tools for studies of atomic physics. The sources of reacting particles in such studies are often spatially extended (Magneto Optical Traps (MOT) or supersonic gas jets), requiring the spectrometers to...
