Automatic Sequencing of an on-Line Gamma Spectroscopy System Using a Microprocessor Controller

A system has been designed for the automatic sequencing and control of spectroscopy experiments for fuel testing in reactors. The system was conceived as part of an integrated data management facility being implemented for the reactor complex at the Chalk River Nuclear Laboratories. A brief description of the system is given and the implications of introducing local "intelligence" in the front-end equipment for automatic data acquisition and experiment control are discussed. A microprocessor unit controls the front end spectroscopy equipment and the experiment according to sequences defined by a remote computer. Experience suggests that commercially available CAMAC modules and spectroscopy equipment do not permit optimum functional partitioning to take full advantage of microprocessors.
