The Response of Optical Isolators in a Nuclear Radiation Environment.
Abstract
The effects of gamma total dose and gamma dose rate exposures on the operation of a state-of-the-art optical isolator were investigated. The isolator was irradiated in both 'on' and 'off' states to determine upset in dose rate environment from 1.5 x 10 to the 8th power to 2.2 x 10 to the 11th power rads(Si)/sec. High state output voltage was subject to upset at all dose rates tested. Propagation delay times, and output voltage and current were measured for total dose exposures up to 5,000,000 rads(Si). Of the parameters tested, only high state output current and low-to-high propagation delay times exceeded the manufacturer's specifications in the total dose environment. (Author)
