IMPROVEMENTS IN AND RELATING TO SIGNAL HANDLING AND PROCESSING

摘要

The invention provides an event monitoring system, the events particularly being neutrons or other emissions from radioactive materials. The event monitoring system comprising a plurality of detector units, at least one of the detector units comprising a detector for the events to be monitored and an amplifier to amplify signals generated by the detector; a signal handler, the signal handler receiving the amplified signals from the detectors, an adder to add to the signals an indication of the detector unit from which the signals originated and a combiner to combine the signals after the addition of the indication; a serial link for conveying the combined signals from the signal handler to a signal processor; and a signal processor, the signal processor including a signal receiver for the combined signals which include the indication of the detector unit, a time stamper for applying to the signal an indication of time of the generation of the signal by the detector unit, and a computer for processing the signals using software to produce information on the signals or events they represent, the processing of the signals using the time and detector unit indications possessed by those signals.
