The SBC experiment and calibration plan

The Scintillating Bubble Chamber (SBC) Collaboration is exploring the dark matter and neutrino potential of liquid-noble bubble chambers. These detectors can observe sub-keV nuclear recoils while being blind to electronic recoils. The SBC-Fermilab liquid argon chamber is currently being assembled for commissioning. Once complete we will measure the detector’s response to nuclear and electronic recoils. The nuclear recoil calibration plan combines photo-neutron sources with a precise Thomson scattering calibration down to the 100 eV target threshold. I will show simulated results demonstrating that this calibration strategy can reach the 5% resolution necessary to probe BSM neutrino physics with a reactor CEvNS measurement. A thermal neutron capture calibration could complement the calibration by tagging events with scintillation light from decay gammas. The scintillation response and electronic recoil response will also be measured with gamma sources. With the scalable target volume, low nuclear recoil threshold, and electronic recoil rejection, the liquid noble bubble chamber is perfectly situated to observe reactor neutrino Coherent Elastic neutrino Nuclear Scattering (CEvNS). A future SBC-CEvNS reactor neutrino experiment using liquid argon and has the potential to achieve the highest statistics CEvNS measurement to date as well as the first definitive reactor CEvNS detection.
