Abstract

The Scintillating Bubble Chamber (SBC) Collaboration isdesigning a new generation of low background, noble liquid bubblechamber experiments with sub-keV nuclear recoil threshold. Theseexperiments combine the electronic recoil blindness of a bubblechamber with the energy resolution of noble liquid scintillation,and maintain electron recoil discrimination at higher degrees ofsuperheat (lower nuclear recoil thresholds) than Freon-based bubblechambers. A 10-kg liquid argon bubble chamber has the potential toset world leading limits on the dark matter nucleon cross-sectionfor 𝒪(GeV/c$^{2}$) masses, and to perform a highstatistics coherent elastic neutrino nuclear scattering measurementwith reactor neutrinos. This work presents a detailed calibrationplan to measure the detector response of these experiments,combining photoneutron scattering with two new techniques to inducesub-keV nuclear recoils: nuclear Thomson scattering and thermalneutron capture.
