Extracting signals of elusive particles from giant chambers filled with liquefied argon

The central piece of the MicroBooNE detector is a liquid-argon time projection chamber — a bus-sized tank filled with argon (kept liquid at a biting minus 303 degrees Fahrenheit). Photo: Reidar Hahn

A revolutionary new kind of neutrino detector sits at the heart of the MicroBooNE experiment at Fermilab. In two new papers published by the Journal of Instrumentation, the MicroBooNE collaboration describes how they use this detector to pick up the telltale signs of neutrinos. The papers include details of the signal processing algorithms that are critical to accurately reconstruct neutrinos’ subtle interactions with atoms in the detector.
