Abstract

A neutron multiplicity counter is designed and calibrated with the integrated electronics data acquisition and processing software described here. The predelay time length search equations are developed by balancing the correlated counts and the background counts of Am-Li neutron sources. A deadtime coefficient fitting method minimizes the root mean square. Nine parameters are acquired and two plutonium samples are used to verify the counter performance and parameter calibration algorithm. Test results show that the design and calibration for neutron multiplicity measurements are valid.
