The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of [superscript 3]He proportional counters to the detector. The purpose of this neutral-current detection (NCD) array was to observe neutrons resulting from neutral-current solar-neutrino–deuteron interactions. We ha...

Description
Summary:The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of [superscript 3]He proportional counters to the detector. The purpose of this neutral-current detection (NCD) array was to observe neutrons resulting from neutral-current solar-neutrino–deuteron interactions. We have developed a detailed simulation of current pulses from NCD array proportional counters, from the primary neutron capture on [superscript 3]He through NCD array signal-processing electronics. This NCD array MC simulation was used to model the alpha-decay background in SNO's third-phase ⁸B solar-neutrino measurement.
