The Largest Liquid Argon Neutrino Detector in the World: ProtoDUNE

ProtoDUNE is helping lead the way for the next generation of long-baseline neutrino experiments, and is exceeding expectations.

DUNE, the Deep Underground Neutrino Experiment, will deploy four massive Liquid Argon Time Projection Chambers (LArTPCs) totaling 40 kilotons of liquid argon to study neutrinos, one of the universe’s most elusive particles. Time Projection Chambers use sensitive volumes of gas or liquid exposed to electric and magnetic fields to reconstruct 3D particle trajectories and interactions. Liquid argon is advantageous for several reasons. It’s relatively inexpensive, produces light when energetic charged particles pass by (scintillates), and won’t absorb electrons produced by ionizing radiation before they reach the detector arrays (since it’s a noble element). It is also very dense, increasing the chances of a particle interacting in the detectors compared to other materials. Click to continue reading on ParticleBites…
