Getting there! DUNE with two 17kt LAr TPC Far Detector (FD1-FD2) modules, a Near Detector Complex and a Neutrino Beam with an intensity of 1.2 MW is well on its way to start physics in 2028 at SURF (SD). Mass Ordering and sensitivity to Maximal CPV - the initial goals of the flagship Long-Baseline (LBL) Neutrino Program - are within reach.
The time has come to define a strategy to achieve the ambitious ultimate precision in the LBL physics goals and possibly further expand the DUNE science scope into the low-energy domain of rare underground physics and BSM searches. Additional LAr mass at the Far Site (DUNE “Phase-II” - FD-3 and FD-4) is absolutely critical to this end.
What is the best strategy to achieve additional mass? Prospects for new credible LAr detector solutions will be presented and discussed in this NPA Seminar.
