A high performance fiber optic telemetry link for use in a space radiation simulator
Abstract
The transmitting end of the fiber optic link is designed to operate in a nuclear and space radiation simulator. It will function without noise increase or other degradation at up to approximately 10 to the 8th power rads (Si)/s of 1-MeV gamma rays and at cryogenic temperatures. The response is linear analog, with a bandwidth of 12 kHz to 350 MHz. Signal inputs are balanced with millivolt sensitivity. All functions are remote controlled through an RS-232 computer interface so that unattended operation is possible. Complete circuit diagrams, a discussion of the design, and test results are given.
