Abstract

The transient radiation-induced absorption in fused silica due to neutron and 7-ray irradiation has been investigated. Transient radiation-induced absorption coefficients (a) at 325 nm have been measured during and after pulsed reactor (TRIGA) irradiation. a increases very rapidly to a maximum value (am x)during a pulse and then decreases asymptotically to a permanent value afterwards. a wassound to reach a maximum value of 0.0070 cm^-1 during a 0.5 MRad reactor pulse and to recover 99% of its initial value to 0.0001 cm^-1 at a time of 1000 s after the reactor pulse.
