Description
The Scintillating Bubble Chamber (SBC) collaboration proposes a superheated liquid argon bubble chamber to detect sub-keV nuclear recoils (NR), enabling detection of both light dark matter scattering and coherent elastic neutrino–nucleus scattering (CE$\nu$NS). The technology is projected to be sensitive to scattering from GeV-mass WIMPs and MeV-energy neutrinos. SBC consists of two projects: SBC-LAr10, a 10 kg liquid argon bubble chamber at the MINOS site at Fermilab used for calibration, and SBC-SNOLAB, a second bubble chamber at SNOLAB aimed at the dark matter search. In this talk, I will present the preliminary results from SBC-LAr10, including representative raw events, gamma rejection performance, and determination of NR threshold. I will also describe next steps for SBC, including an update on SBC at SNOLAB and the potential for novel measurements of neutrinos with a deployment at a reactor source.
