Using Scintillating Bubble Chambers for Dark Matter Detection

The Scintillating Bubble Chamber (SBC) Collaboration is developing a new technology to search for 1-10 GeV/c² WIMP dark matter. The superheated liquid argon (LAr) detector combines noble liquid bubble chambers' excellent electron recoil discrimination, and the event-by-event energy resolution provided by scintillation signals. The experiment has a target nuclear recoil detection threshold of ~100 eV, enabling sensitivity to lower-mass WIMPs compared to past freon bubble chambers. The SBC Collaboration is currently working on two functionally identical 10 kg LAr detectors: SBC-Fermilab commissioned at Fermilab for calibration of low-threshold electron recoil and nuclear recoil responses, and SBC-SNOLAB under development at SNOLAB for our first radio-pure dark matter run using this technology. I will give an overview of the Scintillating Bubble Chamber experiment, with a focus on the SBC-Fermilab detector, which is expected to start collecting data soon.
