PCGAP - APPLICATION TO ANALYZE GAMMA-RAY PULSE-HEIGHT SPECTRA ON A PERSONAL-COMPUTER UNDER WINDOWS NT(R)

PCGAP is a software code, which was written to provide gamma-ray pulse height spectrum analysis on a personal computer platform. The code wa s specifically developed for Windows NT for either an Intel(R) or DEC Alpha(R) based processor. PCGAP includes programs which can be used to control data collection using a Canberra INSPECTOR(R) multichannel pu lse-height analyzer. With suitable spectrum conversion routines PCGAP can be used to analyze data from almost any multi-channel analyzer. Be sides the normal functions associated with a robust spectrum analysis package, PCGAP can be used for radionuclide analysis for actinides via LX and gamma-ray spectrometry. It can be used to control and analyze data from an INEEL developed pulse injection system for individual spe ctrum validation. The package includes programs for the manual analysi s of spectra using displays which permit the spectroscopist to interac tively define the spectral continuum and peak fitting limits, and disp lay the resulting function fitting forms.
