Performance of preshower and shower-maximum detectors with a lead/plastic-scintillator calorimeter

The electron/hadron separation in the calorimetry can be improved if we measure the electromagnetic shower development at an early stage. The incident positions of electrons and photons can be precisely measured with a position sensitive detector placed near the electromagnetic shower maximum. We co...

Description
Summary:The electron/hadron separation in the calorimetry can be improved if we measure the electromagnetic shower development at an early stage. The incident positions of electrons and photons can be precisely measured with a position sensitive detector placed near the electromagnetic shower maximum. We constructed a set of prototype preshower and shower-maximum detectors to be attached in front of a main calorimeter. Performance of the detectors was studied in combination with a lead/plastic-scintillator calorimeter module using high energy beams up to 100 GeV at a test beam facility at Fermi National Accelerator Laboratory.
