A neutron detector circuit for a neutron detector is disclosed that includes a scintillator having a plurality of wavelength shifting optical fibers. A first detection circuit is connected with a first PMT output that is configured to generate a first detection circuit output in response to a first neutron event. A second detection circuit is connected with a second PMT output that is configured to generate a second detection circuit output in response to a second neutron event. A coincidence detection circuit is included that has inputs connected with the first and second detection circuit outputs that is configured to generate a neutron event count output pulse in response to coincident signals being received by the coincidence detection circuit from the first and second detection circuit outputs.
