Patent ID: 8884212

Claim:
Neutron counting method comprising: receiving a pulse sequence from a neutron detector; for each pulse of said pulse sequence: setting said pulse as a trigger pulse triggering a gate, assigning said trigger pulse to a multiplicity category corresponding to the multiplicity of pulses within said gate, determining trigger-to-predecessor intervals from said trigger pulse to pulses preceding said trigger pulse within a range longer than a dead time of said neutron detector; for each multiplicity category: determining the number of trigger pulses assigned to said multiplicity category; building, based upon the trigger-to-predecessor intervals determined, a distribution in time after an arbitrary preceding pulse of trigger pulses assigned to said multiplicity category; estimating, based upon said distribution, a number of trigger pulses lost due to neutron detector dead time that would have been assigned to said multiplicity category; and correcting the number of trigger pulses assigned to said multiplicity category by said estimated number of lost trigger pulses.
