Description
The Scintillating Bubble Chamber (SBC) Collaboration is currently constructing a pair of 10-kg argon bubble chambers for the detection of low-mass (1-10 GeV) WIMPs and coherent scattering of reactor neutrinos (CEvNS). These chambers will be the first physics-scale devices to use superheated noble liquids for the detection of low-energy nuclear recoils. I will review the scintillating bubble chamber technology, including its unique ability to discriminate between electron and nuclear recoils at energies below a keV, and will report on the technical design and construction of the first 10-kg argon chamber. I will describe our plans to calibrate the sensitivity of this device to nuclear recoils down to 100 eV, plans for deployment at SNOLAB for a dedicated low-mass WIMP search, and tentative plans for a reactor CEvNS study.
