Our group at Northwestern recently demonstrated the world's first scintillating bubble chamber, observing simultaneous scintillation and bubble nucleation by nuclear recoils in superheated liquid xenon (arXiv:1702.08861). These detectors already promise unmatched background rejection in searches for canonical WIMP dark matter, and wemare beginning to explore the low-threshold (<=1 keV recoil) capabilities of these devices. Or goal is to establish sensitivity to GeV-mass WIMPs and to coherent elastic scattering of reactor neutrinos. I'll describe the current state of our R&D program and plans for the coming year.
