Abstract :
A lead/liquid scintillator “shashlik” electro-magnetic calorimeter prototype was built and tested. The calorimeter was read out by wave-length shifting optical fibers, running from front to back of the calorimeter, coupled to photomultiplier tubes. The calorimeter was tested at Brookhaven National Laboratory with negative pion and electron beams of momenta between 0.3 and 7.0 GeV/c. The light yield of the calorimeter was measured to be greater than 500 photoelectrons per GeV of incident electromagnetic energy. Analysis shows excellent linearity (better than 2%), an energy resolution of 9%/√E, and a position resolution of 6 mm/√E. This technique can be used to produce large low-cost electromagnetic calorimeters with very fine depth segmentation
