Liquid-noble (scintillating) bubble chambers for CEvNS and low-mass dark matter

• Carl Dahl (Northwestern University)

What do you get when you superheat a noble liquid? The potential answer is a scalable, quasi-background-free method for detecting nuclear recoils at energies as low as 100 eV, enabling both high-statistics reactor CEvNS studies and dark matter searches to the solar neutrino floor/fog at 1 GeV. I'll review the concept behind these detectors, what we've learned from the performance of a small prototype at Northwestern, progress at Fermilab towards the first physics-scale liquid-noble bubble chamber, and our plans to run this new device in the MINOS area to calibrate the sensitivity and background-discrimination capability of the superheated-noble technique.
