Lead scintillation shower detector

Characteristics of the modulus lead-scintillation detector are investigated. A laminated shower detector consisting of moduli 7 radiation lengths each are investigated. Contribution of fluctuation losses of the shower energy to complete resolution is evaluated. It is shown that at the 1 GeV energy of electrons the resolution is 26 %. Total impulse amplitude from two and three moduli increases practically linearly with the electron energy as the energy losses are low: addition of the third modulus results in the amplitude increase by 3-4 %. In three blocks the shower is completely absorbed and energy resolution is determined by inner properties of the detector (lamination), convertor material, identity of light collection conditions. At the electron energy of 3.5 GeV amplitude and resolution remain constant over all square of the detector, except approximately 5 cm zone at the detector edges. The value of this zone is determined by the transverse dimensions of shower and cross section of entering particles
