Beam studies of SAD-150 heavy crystal PWO calorimeter, small angle multiphoton detector of GAMS-4π spectrometer

Small Angle Detector (SAD-150) is a PbWO4 heavy crystal electromagnetic calorimeter with high energy and coordinate resolution for multiphoton events. It has been included in the GAMS-4π setup and calibrated in muon and electron beams. Test measurements of forward emitted π0 and η in the π- p charge exchange reactions with 32.5 GeV/c π- at the IHEP proton synchrotron are reported. The measured mass resolution in the η region agrees with the design value SAD-150 performance does not deteriorate with π- intensities up to 106 π-/s per cell.0SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Beam test results of a PbWO4 crystal calorimeter prototype

Beam tests of an EM-calorimeter prototype made of PbWO4 crystals, produced after significant improvement in growth technology, have been performed at the CERN SPS. The measured energy resolution is σE/E = 2.8%/√E ⊕ 0.47%. © 1995.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
