DUNE is a liquid argon neutrino oscillation experiments located in the Stanford Underground Research Facility (SURF). It has a wide physics program, but one of the mean aims is to investigate, if neutrinos and antineutrinos behave the same.

Neutrinos can travel through dense matter such as the Earth without interacting with a single atom, leaving no trace of their passage. To observe even just a few of the extremely rare interactions of neutrinos with matter, physicists build detectors with massive amounts of target material and operate them for many years. The detectors record the tracks of the particles that emerge from the rare collisions of neutrinos with atoms of the target material.

Neutrino can change flavour (changing from one type to another) when travelling and this process is called neutrino oscillations. The DUNE experiment will determine, if neutrinos and anti-neutrinos will do this in the same way. Any difference observed in this process (this is called CP-violation) might help us to explain why there is more matter than anti-matter in the Universe. We plan to study this process with great precision.

DUNE is a long-baseline neutrino oscillation experiment. It is the flagship particle physics experiment in the US pursued by an international collaboration of almost 1000 physicist from around the world. The DUNE Experiment will use state-of-the-art Liquid Argon Time-Projection Chamber (LArTPC) technology for the massive neutrino detectors planned at the Sanford Underground Research Facility in South Dakota. Active particle detector elements will be immersed in liquid argon (LAr). Argon, a gas at room temperature, condenses to a liquid when cooled below -186°C (-303°F).

DUNE/LBNF is the largest neutrino experiment to-date and PPD is providing essential services to the experiment. A. Weber is currently the UK PI of the experiment, while R. Preece is the project manager. The STFC Technology Department is also involved in the data aquisition system for the detector and in designing a high power neutrino production target.
