Description
Liquid-noble bubble chambers provide a unique opportunity to extend electron/nuclear-recoil discrimination to the O(100)-eV thresholds needed for a GeV-scale dark matter search, while maintaining scalability to the ~ton-year exposures needed to explore the solar neutrino CEvNS fog. I will review what we currently know about the low-threshold performance of these devices and give a status update on SBC-LAr10: a 10-kg argon bubble chamber at Fermilab, built by the SBC Collaboration, that aims to calibrate the nuclear recoil detection threshold of the technique with 10-eV resolution at a target 100-eV threshold. I will also describe progress towards the SBC Collaboration’s first dark matter search, featuring a low-background but functionally identical clone of SBC-LAr10.
