Description
The SBC Collaboration is constructing 10-kg liquid argon bubble chambers with scintillation readout for nuclear-recoil detection. The first device will be commissioned at Fermilab to measure sensitivity to sub-keV nuclear recoils. A second, roughly identical, device will be deployed underground at SNOLAB for a GeV-scale dark matter search. At the same time, the collaboration is exploring sites for a reactor CE$\nu$NS experiment. The technology is expected to provide extreme insensitivity to electron recoils for nuclear-recoil detection thresholds as low as 100 eV, allowing for detection of CE$\nu$NS from reactor neutrinos with a signal-to-background much better than one-to-one, and a possible future program of precision measurements.
