Paper Abstract

A computer-controlled system has been developed for collecting output data from a multiplexer, an individual detector, or a multiplexed array of detectors, and generating pulse height distribution statistics in both tabular and graphical form. Array data from each pixel can be kept separate to produce statistics for each pixel or can be combined to produce statistics for the array as a whole. Both time and voltage thresholds can be established such that only those events above threshold are included in the statistics. The effect of time-dependent drift in the mean value of the outputs can also be minimized by computing a "running mean" which is subtracted from each data point as it is collected. Multiplexed or detector outputs are digitized with 15 bits of resolution at a rate up to 500,000 samples per second. There is no limit to the number of samples that can be collected to generate a given distribution.
