Description

The NOνA collaboration has constructed a 14,000 ton, fine-grained, low-Z, total absorption tracking calorimeter at an off-axis angle to an upgraded NuMI neutrino beam. This detector, with its excellent granularity and energy resolution, and relatively low-energy neutrino thresholds was designed to observe electron neutrino appearance in a muon neutrino beam, but it also has unique capabilities suitable for more exotic efforts. In fact, if an efficient upwardgoing muon trigger with sufficient cosmic ray background rejection can be demonstrated, NOνA will be capable of a competitive indirect dark matter search for low-mass WIMPs. The cosmic ray muon rate at the NOνA far detector is about 100 kHz and provides the primary challenge for triggering and optimizing such a search analysis. The status of the NOνA upward-going muon trigger is presented.
