In pursuit of the five science drivers, the 2014 report identified three "high priority large category" projects meriting significant investment in the FY2014–2023 period, regardless of the broader funding situation: the High Luminosity Large Hadron Collider (a proposed upgrade to the Large Hadron Collider located at CERN in Europe); the International Linear Collider (a proposed electron - positron collider, likely hosted in Japan); and the Long Baseline Neutrino Facility (an expansion of the proposed Long Baseline Neutrino Experiment (that was renamed the Deep Underground Neutrino Experiment), to be constructed at Fermilab in Illinois and at the Homestake Mine in South Dakota).
