Abstract :
A multiwire proportional chamber has been developed to study the properties of a detector for tracking of low energy electrons (0.2–1 MeV). The geometry and the materials used have been optimized to minimize energy losses and multiple Coulomb scattering. The detector is equipped with a special electronic readout and event selection system, consisting of an amplifier/comparator stage, a fast trigger unit and a data multiplexer. The fast trigger system identifies the desired events within 30 ns. Based on this prototype, the full scale detectors (50×100 cm2) will be constructed to determine the electron tracks in neutron decay experiments.
