Abstract--This report summarizes the radiation damage and the
light transmission efficiency studies done on air core light guides
with three different types of reflective material: two types of alu-
minized Mylar and a highly reflective plastic film from 3M called
Radiant Mirror Film. The variations in light transmission efficien-
cies of these reflective materials have been studied with respect to
the wavelengths of the incident light. The light transmission with
one type of aluminized Mylar, which shows better reflectivity in
UV range, deteriorated 14% after 10 Mrad of -ray irradiation
from a 9.5 kCurie 137Cs source. Light guides with the other type
of aluminized Mylar and Radiant Mirror Film do not seem to be
affected from radiation, and they show superior light transmission
efficiency in the visible region.
Index Terms--Air core light guide, aluminized mylar, HEM,
light guide, light transmission, radiation hardness, reflective film.
