研究了对反应堆中微子的相干弹性中微子核散射 (CE ν NS) 敏感的低阈值 (100 eV) 闪烁氩气泡室的物理范围。分析了对弱混合角、中微子磁矩和轻 Z (cid:48) 规范玻色子介体的敏感性。对背景进行蒙特卡罗模拟以评估它们对信号的贡献。分析表明，距离 1 MW 研究堆 3 m 处的 10 kg 腔室或距离 2000 MW 动力堆 30 m 处的 100 kg 腔室暴露一年，可实现世界领先的灵敏度。这种探测器有潜力成为利用核反应堆研究 CE ν NS 的领先技术。
The physics reach of a low threshold (100 eV) scintillating argon bubble chamber sensitive to Coherent Elastic neutrino-Nucleus Scattering (CE ν NS) from reactor neutrinos is studied. The sensitivity to the weak mixing angle, neutrino magnetic moment, and a light Z (cid:48) gauge boson mediator are analyzed. A Monte Carlo simulation of the backgrounds is performed to assess their contribution to the signal. The analysis shows that world-leading sensitivities are achieved with a one-year exposure for a 10 kg chamber at 3 m from a 1 MW th research reactor or a 100 kg chamber at 30 m from a 2000 MW th power reactor. Such a detector has the potential to become the leading technology to study CE ν NS using nuclear reactors.
