The Neutral Current Detector Phase of the Sudbury Neutrino Observatory

The Sudbury Neutrino Observatory (SNO) has recently started taking data in the Neutral Current Detector (NCD) phase, in which an array of forty $^3$He- and $^4$He-filled proportional counter strings has been added to SNO's heavy water to detect neutrons liberated in neutral current interactions of neutrinos with deuterium. Pulse shape analysis of digitized current pulses from the NCDs is used to achieve the background rejection necessary to extract the neutral current signal. Alphas from uranium and thorium contamination in the NCD bodies are the primary physics background to the NCD neutron signal. This talk will focus on the NCD analysis techniques under development, and, in particular, emphasize techniques for discrimination against alpha backgrounds.
