The paper offers an original approach based on ADC sampling of the incoming detector pulses, accumulating and storing the input information into PC memory, which is then processed by specialized software. This allows one to process many times the stored detector information, without losing some part of the incoming pulses that fall into the dead-time interval for measurement and categorization after each pulse as is the case with traditional spectrometric systems. The system uses 8bits ADC with 10ns sampling step and buffer memory of 32K. The received information is directed to the PC by means of a parallel port. The created system for automatic start of measurement ensures that the input information is stored in files on the PC hard disk. The accumulated information is processed by means of the software, designed by the team, that allows us to define (on the basis of strict mathematical criteria) the informative parameters of each pulse, to get the amplitude spectrum etc., through the analysis and digital filtration of each pulse. The research is part of a phase in the process of developing ‘A new method for simultaneous time-energy spectral analysis for application in optical and nuclear technologies’, funded by the National Science Fund, project Ph-1206/02. |
