MicroBooNE

The MicroBooNE (Micro-scale Booster Neutrino Experiment) detector is based at Fermilab (Batavia, IL, USA), and was built to investigate the nature of the ‘low energy excess’ phenomenon—an excess of electron-neutrino candidate events in data collected by MiniBooNE (a Cherenkov detector experiment for designed to measure short-baseline neutrino oscillations), compared to the predicted number. This had implications for the possible existence of a sterile neutrino, a hypothetical particle that could be a dark matter candidate. As well as looking for these, the detector also aims to make precise measurements of low-energy neutrino-argon cross sections, which is crucial for furthering our understanding of neutrino interactions. MicroBooNE has an active volume of 80 tonnes of liquid argon, filling a time projection chamber measuring 2.56 m in width,  2.30 m in height, and 10.37 m in length.

MicroBooNE was operational between 2015 and 2021 and took five runs of data during this time; work in Edinburgh, led by Dr Andrzej Szelc, focuses on analysing this data to extract electron neutrino cross sections and understanding the behaviour of scintillation light in argon.
