As part of our efforts to promote international participation in the DUNE collaboration, we organized a Europe-focused meeting for the 7th and 8th April at CERN. On the morning of the 7th, the CERN Research Director, Eckhard Elsen, welcomed seventy scientists from thirteen European nations, including several existing DUNE collaborators.
Eckhard explained the global vision for particle physics and the importance of the CERN neutrino platform in supporting LBNF/DUNE. The Director of Fermilab, Nigel Lockyer, followed with a talk introducing the background to LBNF/DUNE and highlighting the high-level support from the U.S. DOE and CERN. The remainder of the talks on the first day described the systems and activities that make up LBNF/DUNE, including the beamline, the far detector and the near detector complex, while underscoring the essential role that the CERN neutrino platform plays in the experiment, in particular for the two ProtoDUNE detectors.
The second day focused on the opportunities available in LBNF/DUNE for contributions by new groups. Given that the two large-scale ProtoDUNE detectors will be constructed and operated at CERN — in the heart of Europe — this topic proved popular.
The lively and constructive discussions that took place during the meeting demonstrated a great deal of interest and a number of new groups are considering joining DUNE. Based on the positive collaborative spirit of this meeting, we are optimistic that DUNE and LBNF will soon enjoy increased European participation, thereby strengthening our prototyping efforts at CERN.
