Abstract

We report the result of evaluating radiation damage to Bicron BC408 plastic scintillator used in the DOslash Luminosity Monitor during Run IIa. The Luminosity Monitor provides pseudo-rapidity coverage over the range 2.7 < |eta| < 4.4, with the radiation dose in Run IIa estimated to be 0.5 MRad for the region closest to the beams. We find the light yield is degraded by 10-15 % due to radiation damage by comparing new and old scintillator in four observables: (i) visual inspection, (ii) optical transmittance, (iii) response to the radioactive source of ⁹⁰Sr and (iv) light yield for cosmic rays.
