Deep Underground Neutrino Experiment
The Deep Underground Neutrino Experiment (DUNE), formerly the Long Baseline Neutrino Experiment (LBNE) is a proposed neutrino detector at the Homestake Mine which would observe neutrinos produced at Fermilab. It would 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).
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. These include Liverpool, Manchester, Sheffield, Cambridge, Oxford, and University College London.
It is planned to be operational in 2022.
Dissolution and Successor
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." The LBNE collaboration was officially dissolved on Jan. 30, 2015, shortly after the new collaboration recommended by P5 was formed on Jan. 22, 2015. The new collaboration selected the name Deep Underground Neutrino Experiment (DUNE).
