Abstract :
A series of high-dose-rate and low-dose-rate irradiations of a large sample of plastic scintillating fibers has been completed. Measurement results of the transmission characteristics of the fibers are presented. The transmission measurements showed striking features: (1) those fibers irradiated slowly in air suffered the greatest level of damage, (2) the fibers irradiated rapidly, and then allowed to recover, displayed the least amount of damage, and (3) fibers irradiated slowly in argon displayed a level of damage intermediate between the other two. One fiber, the green-emitting SCSF-Y8, was the only exception, and showed no difference in the level of damage observed in the three modes of irradiation
