Search for fast magnetic monopoles with NOvA Far Detector.

The NOvA experiment at Fermilab consists of two functionally identical liquid scintillator detectors, the Near Detector and the Far Detector, to study neutrino oscillations using GeV-scale neutrinos from the Fermilab NuMI beam. Due to its location close to the earth's surface, surface area of 4000 m², and little overburden, the NOvA Far Detector is sensitive to an extensive range of magnetic monopole masses and velocities. With the help of the Far Detector, we are looking for signals of relic monopoles in the cosmic ray flux that might have been produced in the early universe. We have developed a software trigger that continously searches the data stream composed of mostly a kHz of cosmic rays for signals that resemble a magnetic monopole, to ensure a monopole crossing the detector will be recorded for later analysis. The magnetic monopoles are expected to deposit enormous energy through ionization. We have set up a test stand to study the detector electronics response to such a huge signal. In this talk, I will present the status of the search for fast-moving magnetic monopoles with NOvA Far Detector.
