A Multiparameter Data Acquisition and Display Program

A general purpose multiparameter data-acquisition, histogramming and display program is presented. The 32 input parameters of the program consist of up to 16 CAMAC words of 16 bits, and up to 16 algebraic functions of these words. Up to 64 one and two-dimensional histograms based on these parameters can be constructed, subject to up to 144 correlated conditions imposed on the input parameters. The display system consistsof a rapid refresh scope with 10 bit X and Y resolution, and a push-button panel, specifically designed to interact dynamically with either the display or the data acquisition programs. Typical event rates vary between 300 Hz and 10 kHz, depending on the number of histograms generated and on their filtering conditions.
