Calibration of the Scintillating Bubble Chamber (SBC)

The Scintillation Bubble Chamber (SBC) is a dark matter detector designed to search for Weakly Interacting Massive Particles (WIMPs). By combining the nuclear recoil sensitivity of bubble chambers with the detection of scintillation light, the SBC aims to achieve high efficiency for dark matter detection. The SBC-Fermilab device, a 10kg liquid argon prototype, is scheduled to begin operations for calibration and initial data collection in the shallow underground NuMI tunnel at Fermilab in early 2025. My presentation at APS will focus on the calibration of SBC nucleation efficiency using several sources of argon recoils, including Thomson scattering, photoneutron sources, and thermal neutron captures.
