Deep Underground Neutrino Experiment

The Deep Underground Neutrino Experiment (DUNE), formerly the Long Baseline Neutrino Experiment (LBNE) is a proposed neutrino experiment with a near detector at Fermilab and a far detector at the Sanford Underground Research Facility which will observe neutrinos produced at Fermilab. It will fire an intense beam of trillions of neutrinos from a production facility near Fermilab (in Illinois) over a distance of 1,300 kilometres (810 mi) to an instrumented multi-kiloton volume of liquid argon located at the Sanford Lab in South Dakota. The proposed detector is to be about 12 metres (39 ft) across. Its goal would be to study neutrino oscillation and perhaps determine whether neutrinos are their own anti-particle, that is whether they are Majorana particles. Part of the path of the neutrinos would take them 30 kilometres (19 mi) underground (the beam itself will start 1.5 kilometres (4,900 ft) under the surface).[1]

Funding and construction

The US has committed $1 billion to its development. The UK has announced that they will help fund the project and nine British universities will be involved.[1] These include Lancaster, Liverpool, Manchester, Sheffield, Cambridge, Oxford, and University College London.

It is planned to be operational in 2022.

History

The Particle Physics Project Prioritization Panel (P5) concluded in its 2014 report that the research activity being pursued by LBNE "should be reformulated under the auspices of a new international collaboration, as an internationally coordinated and internationally funded program, with Fermilab as host."[2] The LBNE collaboration was officially dissolved on Jan. 30, 2015,[3] shortly after the new collaboration recommended by P5 was formed on Jan. 22, 2015.[4] The new collaboration selected the name Deep Underground Neutrino Experiment (DUNE).[5]
