A liquid argon scintillating bubble chamber for CEνNS reactor neutrino detection and dark matter search

The Scintillating Bubble Chamber is a novel detector based on 10 kg of LAr that is currently under construction at Fermilab (Chicago, USA). This detector is projected to reach a threshold of 100 eV and will take advantage of the excellent electromagnetic background discrimination characteristic of bubble chambers to measure neutrinos from nuclear reactors via coherent elastic neutrinonucleus scattering (CEνNS). The physics reach of the bubble chamber is studied for the cases of non-standard interactions through a new gauge boson Z, the weak mixing angle and the neutrino magnetic moment. A second bubble chamber will be placed in SNOLAB to search for dark matter in the form of weakly interacting massive particles (WIMPs), for that reason an extensive background program is being developed to keep all backgrounds to less than 1 event per year
