14:00 Probing new physics with Coherent Elastic Neutrino-Nucleus Scattering and the future Ricochet experiment

The measurement of Coherent Elastic Neutrino-Nucleus Scattering (CENNS) has been a holy grail in neutrino physics since its prediction almost 40 years ago, and has now become a burgeoning field of research following its recent discovery by the COHERENT collaboration in July 2017. Following this first detection, the future Ricochet experiment aims at searching for new physics in the electroweak sector by providing the first low-energy and high-precision measurement of CENNS down to the O(10) eV energy-scale, where new physics signatures may arise. These include for instance the existence of sterile neutrinos and of new mediators, that could be related to the DM problem, and the possibility of Non Standard Interactions that would have tremendous implications on the global neutrino physics program. Thanks to a recently awarded ERC starting grant, the collaboration is building a kg-scale cryogenic detector, with outstanding sensitivity to low-energy nuclear recoils, that will be deployed at an optimal nuclear reactor site within the forthcoming Ricochet neutrino experiment. The key feature of this proposed detector technology is to combine two target materials: Ge-semiconductor and Zn-superconducting metal, both achieving O(10) eV energy thresholds with unparalleled background rejection capabilities. As this proposed detector, called CryoCube, is expected to reach a 5-sigma level CENNS detection significance in a only a couple of days at a nuclear reactor site as ILL, it will be uniquely positioned to probe various new physics scenarios after only one year of data taking

14:30 DAMIC-M

The DAMIC experiment uses thick fully-depleted charge-coupled devices (CCDs) to search for low-mass dark matter particles. The low pixel readout noise and leakage current make DAMIC extremely sensitive to ionization signals from the interaction of dark matter particles with nuclei or electrons in the silicon target. The CCDs' excellent energy and spatial resolutions, provide unique capability to identify surface and bulk radioactive backgrounds. Since early 2017, DAMIC has collected data with 40-gram silicon target installed in the SNOLAB underground laboratory. An upgrade of the detector, DAMIC-M, to be installed at the Laboratoire Souterrain de Modane, features a kg-size silicon target and unprecedented single electron resolution resulting in a detection threshold as low as 2 ionized electrons. We will review the key components of the experiment, the current results and the status of DAMIC-M

15:00 Analysis of the light production and propagation in the 4 tonne dual-phase demonstrator

The Deep Underground Neutrino Experiment (DUNE) is a new generation long-baseline neutrino detector conceived to answer fundamental questions regarding neutrino physics. DUNE proposed to increase the sensitivity on the CP-violation, and search for supernova neutrino burst and proton decays. To pursuing these goals, DUNE planned to install four giant Liquid Argon (LAr) Time Projection Chambers (TPC) with an active volume of 10-kton, using both single and dual- phase (DP) technology. The latter provides charge amplification before collection in the gaseous phase but, so far, it has never been tested in such a big scale. A DUNE DP prototype (ProtoDUNE-DP, 6x6x6 m3 LAr volume) is currently being constructed at CERN. In 2017, a DP 4 tonne demonstrator of 3x1x1 m3 volume took cosmic data and exhibited good performance in terms of charge extraction and light collection. The photon detection system in these detectors is crucial to provide the trigger signal for rare non-beam events, to give an absolute time reference for the charge and to complementary calorimetry.
An overview of the 3x1x1 light detection system performance will be presented. Preliminary results on the electron recombination in the LAr, the de-excitation mechanisms of LAr atoms, sensitivity on the LAr optical parameters and on the LAr purity monitoring will be shown.
