JIGSAW: a gamma ray data acquisition, display and analysis program

The authors report on work performed to date on JIGSAW, a self-contained data acquisition, display, and analysis system designed to collect data from multiple gamma-ray detectors. The data acquisition system utilizes commercially available VMEbus and NIM hardware modules, and the VME exec real-time operating system. A Unix-based software package, written in ANSI standard C and with the X11 graphics routines, allows the user to view the acquired spectra. Analysis of the histograms can be performed in background during the run with the ROBFIT (R.L. Coldwell and G.J. Bamford, 1991) suite of curve fitting routines.<>
