论文摘要
我们报告了液体氙气成核所需的过热温度的第一个精度测量值为$Δt_{wall，onb} $ =（16.9 $ \ pm $ 0.5）k和$Δt_{wall，onb} $ =（19.2 $^{+0.4} {+0.4} _ {+0.4} _ { - 1.11} $ 02 $ 0.98 bar and p = $（1.32^{+0.05} _ { - 0.01}）$ bar。两者均以$ \ sim $ 162 K的亚冷干液温度进行测量。专用的液体氙气设置用于测量气泡成核首先出现在电阻的平坦表面上的温度。使用流体动力学模拟确定电阻表面上相关的平均热通量。未来的实验可以使用这些实验结果来确定液体氙气沸腾的可能性，并设计有效的热汇，以防止气泡成核。
We report the first precision measurement of the superheat temperature required for bubble nucleation in liquid xenon of $ΔT_{wall,ONB}$ = (16.9$\pm$0.5) K and $ΔT_{wall,ONB}$ = (19.2$^{+0.4}_{-1.1}$) K at pressures of P = $(0.98\pm0.02)$ bar and P = $(1.32^{+0.05}_{-0.01})$ bar, respectively. Both are measured at a subcooled bulk fluid temperature of $\sim$ 162 K. A dedicated liquid xenon setup is used to measure the temperature at which bubble nucleation first appears on the flat surface of a resistor. The associated average heat flux at the surface of the resistor is determined using fluid dynamics simulations. Future experiments can use these experimental results to determine the likelihood of boiling in liquid xenon and to design effective thermal sinks that prevent bubble nucleation.
