Its sampling frequency is 1.5" and the sampling medium is 1/4" Kyowa SCSN-61T polystyrene based scintillator. Y7 Kyowa WLS was used to collect light into 8 Hamamatsu R2154 photomultipliers. A monitoring system has been built for the calorimeter. A LSI UV laser pumps a sample of SCSN-61T, which emits light that is subsequently shifted by Y7 and transported to the PM's via jacketted 1 mm acrylic fibers. It simulates the passage of a charged particle. A PIN photodiode also monitors the light output, for cross reference with the PM's. Interspersed among the steel and scintillator, there are 6 PWC's whose purpose is to discriminate between electromagnetic and hadronic showers. Some position information can be gathered. The PWC inter-wire spacing is approximately 1 cm. (Abstract shortened with permission of author.)123 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
