Abstract

The booster instrumentation uses analog and digital fiber-optic links, designed to withstand at least 50 krads without performance degradation. The links use inexpensive and commercially available components that operate at a center wavelength of 820 nm. The analog link operates at 30 MHz over a 200-m fiber and can provide insertion gain. The digital link provides 60-ns timing pulses without the dispersive effects of coaxial cables. The optical fiber is a step-index hard clad silica type with a 200- mu m core. Component selection criteria, link design, installation, testing and performance for the optical links in the Booster instrumentation systems are presented. >
