Description
During the past decades experiments using liquid xenon as a detector material have grown rapidly in the fields of dark matter and neutrino searches. During the scale up of such detectors there is a big push to move the electronics closer to the detectors which are submerged in cryogenic noble gases. One such example is the development of ASICs operating in liquid xenon for the amplification and digitization of charge and light signals. A big question is how much heat can be generated before these chips creates bubbles (nucleate boiling) in the xenon. Such bubbles could create high-voltage, pressure and electronic noise problems within a detector. We report the first precision measurement of the superheat temperature required for bubble nucleation in liquid xenon of Δ Twall,ONB = (16.9±0.5) K and Δ Twall,ONB = (19.2+0.4−1.1) K at pressures of P = (0.98±0.02) bar and P = (1.32+0.05−0.01) bar, respectively. In this talk we will present the results together with the video material of creating bubbles in liquid xenon.
