Low-Threshold Response of a Scintillating Xenon Bubble Chamber to Nuclear and Electronic Recoils
arXiv.org
07 Oct 2024
Abstract
A device filled with pure xenon first demonstrated the ability to operate
simultaneously as a bubble chamber and scintillation detector in 2017. Initial
results from data taken at thermodynamic thresholds down to ~4 keV showed
sensitivity to ~20 keV nuclear recoils with no observable bubble nucleation by
$\gamma$-ray interactions. This paper presents results from further operation
of the same device at thermodynamic thresholds as low as 0.50 keV, hardware
limited. The bubble chamber has now been shown to have sensitivity to ~1 keV
nuclear recoils while remaining insensitive to bubble nucleation by
$\gamma$-rays. A robust calibration of the chamber's nuclear recoil nucleation
response, as a function of nuclear recoil energy and thermodynamic state, is
presented. Stringent upper limits are established for the probability of bubble
nucleation by $\gamma$-ray-induced Auger cascades, with a limit of
$<1.1\times10^{-6}$ set at 0.50 keV, the lowest thermodynamic threshold
explored.
