Computer aided digitized microscope (CADIM) for nuclear emulsion analysis

Abstract The CADIM apparatus is a combination of : (a) a microscope equipped with a motorized stage and a drawing attachment; (b) high precision digitizers of X , Y and Z coordinates; (c) television camera, monitors and tape recorder; (d) a microcomputer and its peripherals. In addition to fast scanning and measurements in nuclear emulsion, it enables the performing of a direct visual comparison between the topology of an event seen in emulsion and its reconstructed topology from the data taken by associated electronic detectors. The use of television techniques allows image display and storing. This apparatus will be used in the first place for the CERN hybrid experiment WA71 searching for beauty particles.
