In this paper, we propose a new approach for online detection of pileup in gamma-ray spectroscopy using finite length deconvolution filters. The approach was tested in resolving pileup with an average success of 93%. We show that the number of pileup events can be reduced by eightfold using the proposed approach. Gamma pulses, from a 3 inch Na(Tl) scintillation detector, were captured as single and double pulses for the purpose of testing the proposed peak detection algorithm. The algorithms developed here were then implemented in real time using a high performance floating-point processor, TMS320C6711.
