The design, principle of operation and the results of the first measurements made with a 4-channel multiplexed analyzer for real-time parallel processing of fast scintillation detectors is described. Recent advancements in the performance of organic scintillation media for the detection of fast neutrons, not least the reduction in hazard and the recent advent of plastic scintillation materials exhibiting Pulse Shape Discrimination (PSD), has highlighted the possibility of using multiple detectors in systems based on detectors exploiting these media. In this paper a real-time, digital multiple-channel PSD analyzer is described based on a single-board solution with an integrated high-voltage supply and graphical user interface. It has been developed to meet the requirements of nuclear materials assay of relevance to safeguards and security, and tested in a variety of related laboratory-based environments.
