The NOvA power distribution system
TL;DR: In this article, the authors describe power distribution systems and grounding schemes built for the near and far detectors of the NOvA long-baseline neutrino experiment, which are used to power the avalanche photodiodes and their thermoelectric coolers, the front-end boards that read out, digitize and time stamp the signals from the signals, and the data concentrator modules used to receive and format the data from the front end boards before sending them to a farm of computers used to build the events.
The NOνA experiment
TL;DR: NOνA as mentioned in this paper is a long-baseline neutrino experiment designed to study ν====== μ� →ν¯¯¯¯ e¯¯¯¯ and $\overline
u_{\mu} \to \overline $¯¯ $¯¯ oscillations.

TL;DR: In this paper, photoelectron yields of extruded scintillation counters with titanium dioxide coating and embedded wavelength shifting fibers read out by silicon photomultipliers were measured at the Fermilab Test Beam Facility using 120 GeV protons.

TL;DR: In this paper, the authors proposed a data-driven triggering scheme that continuously searches the NOvA far detector's live data stream for monopole-like patterns, which can be used for the first magnetic monopole search.

TL;DR: In this article, a software-based trigger is designed to make decisions based on the data recorded by the NOvA far detector, which is sensitive to the detection of magnetic monopoles over a large range of velocities and masses.
