Automatic track countings
For convenient utilization of track detectors, results must be obtained quickly, so automatic processes are usually employed. To this end two techniques are investigated : spark counter and quantimet system. The first one is appropriate for low densities (below 4000 tracks/cm2) ; for densities between 4000 tracks/cm2 and 2.2 105 tracks/cm2 counting is performed with a Cambridge Quantimet 720 ; for higher densities, two different methods are described which take into account the overlapping of tracks.
