Spectra from foil-excited molybdenum ions

Description: The extreme-ultraviolet spectra (5 to 55 nm) for foil-excited molybdenum ions have been measured using 22 to 200 MeV beams from the Brookhaven National Laboratory MP tandem Van de Graaff accelerator facility, 20 ..mu..g/cm/sup 2/ C stripping foils, and a grazing incidence spectrometer. The mean ion charge states (13 to 28) and the narrow distribution widths (about 2 charge states) were accurately predictable from experimental parameters. Where possible, comparisons are given with Mo radiation f… more

Data Handling for the Wide-Angle Hall Jet Experiment

Description: The data handling needs for a jet production experiment in the wide-angle hall are discussed. The several layers of triggering and a data acquisition system were designed, the configuration of the local intersection computer system was discussed, and the time required to analyze a typical event was estimated. It was concluded that the experiment does not appear to place unrealistic demands on detector technology. The slow trigger was believed to be the crucial aspect of the experiment. 15 figur… more

Report of the subgroup on fast processing

Description: A study was made of the flow of data and the simultaneous processing needed to reduce the 10/sup 7/ to 10/sup 8/ triggers per second expected at ISABELLE to a number of events on the order of 10 to 100 per second which would be written on magnetic tape. It was assumed that within 100 ns of the event a fast pretrigger would have reduced the data rate to at most 10/sup 7/ per second. At that point, data from all sense elements in the experiment would be fed into a 1-..mu..s-long pipeline. Within … more
