| Abstract;A new high-speed multiple pulse time data registration, processing and real-time display system for time interval analysis (TIA) was developed for counting either .BETA.-.ALPHA. or .ALPHA.-.ALPHA. correlated decay-events. The TIA method has been so far limited to selective extraction of successive .ALPHA.-.ALPHA. decay events within the milli-second time scale owing to the use of original electronic hardware. In the present pulse-processing system, three different high-speed .ALPHA./.BETA.(.GAMMA.) pulses could be fed quickly to original 32 bit PCI board (ZN-HTS2) within 1.MU.s. This original PCI board is consisting of a timing-control IC (HTS-A) and 28 bit counting IC (HTS-B). All channel and pulse time data were stored to FIFO RAM, followed to transfer into temporary CPU RAM (32 MB) by DMA. Both data registration (into main RAM (200 MB)) and calculation of pulse time intervals together with real-time TIA-distribution display simultaneously processed using two sophisticate softwares. The present system has proven to succeed for the real-time display of TIA distribution spectrum even when 1.6*10'5' cps pulses from pulse generator were given to the system. By using this new system combined with liquid scintillation counting (LSC) apparatus, both a natural micro-second order .BETA.-.ALPHA. correlated decay-events and a millii-second order .ALPHA.-.ALPHA. correlated decay-event could be selectively extracted from the mixture of natural radionuclides.
