Commissioning of a LAr Scintillating Bubble Chamber for WIMP Dark Matter Detection*

The Scintillating Bubble Chamber (SBC) collaboration is constructing two 10 kg LAr bubble chambers for the direct detection of GeV-scale dark matter and coherent elastic neutrino-nucleus scattering (CEvNS). Calibration of the chamber will occur at Fermilab with the SBC-LAr10 detector. The low-background dark matter search will take place at SNOLAB, with a second functionally identical chamber, SBC-SNOLAB. Scintillating bubble chambers combine the electron-recoil insensitivity of bubble chambers with scintillation discrimination to achieve low nuclear recoil thresholds. With a target nuclear recoil threshold of 100 eV, SBC aims to probe unexplored WIMP dark matter parameter space. With great potential for neutrino detection via the CEvNS channel, future plans may consist of deploying a bubble chamber at a reactor site. The status of SBC-LAr10 commissioning will be discussed, along with an overview of the SBC experiment.
