Radiation damage studies for the SDC electromagnetic calorimeter

We report the results from a year long study aimed at radiation resistance and optical performance of scintillator tile with green wave shifter fiber readout. After careful investigation of several rad-hard plastic scintillators from Bicron and Kuraray, studies indicate that for a specific rad-hard Bicron scintillator, it is possible to build a tile/fiber EM calorimeter that can operate in the design luminosity of SSC. This calorimeter with excellent optical response would only have a light loss of about 5% after being exposed to 1 Mrad. (author)
