Research investigating the application of pressure-cycled bubble chambers to fast neutron detection is described. Experiments with a Halon-filled chamber showed clear sensitivity to an AmBe neutron source and insensitivity to a (137)Cs gamma source. Bubble formation was documented using high-speed photography, and a ceramic piezo-electric transducer element registered the acoustic signature of bubble formation. In a second set of experiments, the bubble nucleation response of a Freon-134a chamber to an AmBe neutron source was documented with high-speed photography.
描述了关于压力循环气泡室在快中子探测中应用的研究。用充满哈龙的气泡室进行的实验表明，其对镅铍中子源有明显的灵敏度，而对铯-137伽马源不敏感。使用高速摄影记录了气泡的形成过程，并且一个陶瓷压电换能器元件记录下了气泡形成的声学特征。在第二组实验中，用高速摄影记录了氟利昂-134a气泡室对镅铍中子源的气泡成核响应。
