The NO ν A Far Detector Data Acquisition System

The NOνA experiment is a long-baseline neutrino experiment designed to make measurements to determine the neutrino mass hierarchy, neutrino mixing parameters and CP violation in the neutrino sector. In order to make these measurements the NOνA collaboration has designed a highly distributed, synchronized, continuous digitization and readout system that is able to acquire and correlate data from the Fermilab accelerator complex (NuMI), the NOνA near detector at the Fermilab site and the NOνA far detector which is located 810 km away at Ash River, MN. This system has unique properties that let it fully exploit the physics capabilities of the NOνA detector. The design of the NOνA DAQ system and its capabilities are discussed in this paper.
