TWO PARAMETER MULTICHANNEL PULSE-HEIGHT ANALYZER
A system is described in which a conventional single parameter multichannel analyzer is used as a two parameter analyzer. A two parameter selector which selects the coincident events to be studied and the memory section to store them, was developed. Each of the coincident pulseheight distributions, from the two detectors, is applied to one set of deflection plates of a 5-in. cathode-ray tube. While the multichannel analyzer accumulates the X spectrum, a live'' intensity modulated X-Y map,'' with a resolution of 100 x 128 channels, may be seen on the CRT screen and stored on polaroid film. Four spectral regions can be selected from this spectrum simultaneously by means of digital windows, each to be stored in one quadrant (128 channels) of the memory of the multichannel analyzer. These spectra can then be read out of the memory with the available multichannel analyzer output equipment. Since digital windows are used rather than conventional single channel analyzers, high resolution and good energy accuracy are achieved. (auth)
