On-Line Processing of Data from Large Scale Experiments at PPPL

DAS-1800, a data acquisition system built around an IBM-1800 computer, has been installed and is being used in conjunction with the larger experimental machines at PPPL. An enumeration of the purchased equipment and the rationale for choosing it are given, as well as the overall philosophy and some details of peripheral equipment designed and fabricated in house. Software, including IBM-supplied monitors, locally written systems programs, and the experimenters' user programs, is discussed. Finally, a summary is given of DAS-1800 applications to the experiments on the PPPL machines.
