Claim One:
1. A standalone multichannel analyzer (MCA) for collecting and analyzing radiation data, comprising: a preamplifier for converting a charge pulse of a radiation detection event into an analog signal characterized by a step rise from an external preamplifier; an anti-aliasing filter for bandlimiting the analog signal and having means for adjusting gain and offset; an analog to digital converter (ADC) which converts the analog signal from the anti-aliasing filter to a digital signal; and a digital processor for processing the digital signal to produce an energy and time associated with the arrival of each radiation pulse, said digital processor including a pulse shaping filter for converting the step rise of the charge pulse into a unipolar shaped pulse, and an adaptive predictive filter for removing a predicted signal from the output of the pulse shaping filter.
