The signal shape of a tower-type ionization calorimeter

Abstract The electrical model of an ionization calorimeter tower with 20×25 cm 2 lateral size and 6 nuclear lengths longitudinal size is studied experimentally. The signal propagation time along the tower structure is shown to be 160 ns, the tower characteristic impedance is 5 Ω. The signal is significantly influenced by dispersion. The high counting rate operation of the calorimeter concerned requires perfect termination of the detector characteristic impedance to the amplifier input impedance.
