What is ProtoDUNE

The international neutrino physics community has come together to develop the Deep Underground Neutrino Experiment (DUNE), a leading-edge experiment for neutrino science and proton decay studies. This experiment, together with the facility that will support it, the Long-Baseline Neutrino Facility (LBNF), will be an internationally designed, coordinated and funded program, hosted at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois.

The CERN single-phase liquid argon prototype detector at CERN (protoDUNE-SP) is a crucial milestone for the DUNE experiment that will inform the construction and operation of the first 10 kt DUNE far detector module. The prototype detector and beam test serve two principal functions

protoDUNE-SP Goals:

  • Validate construction techniques and operational performance of full-scale single-phase TPC prototype modules on the time scale needed to begin construction of first underground 10 kt module (late 2019).
  • Measure and study the response of the detector to charged particles of different types and energies. Results from these measurements serve to assess systematic detector uncertainties and validate MC simulations. They also enable validation and tuning of event reconstruction algorithms and particle identification tools.

Experience gained from construction, installation and commissioning of protoDUNE-SP as well as performance tests with cosmic ray data are expected to lead to a detector optimization of equivalent phases for the DUNE far detector.
