The Radiation Area Monitoring System at NAL

A digital multiplexing system for monitoring radiation levels adjacent to approximately eight (8) miles of beam line with over 500 detectors is being implemented at NAL. Data from individual detectors is collected in a central area via a dedicated-time-slot digital multiplexing system, designed for high reliability rather than high bit rates, and is completely independent of any accelerator control system. Data processing is performed in a hardwired core memory system, and record keeping is accomplished via a link to the Accelerator Control Computer. A wide variety of oscilloscope displays are available for selective intensification of data.
