探测器计数低能量（小于1兆电子伏）的电离事件在液氦的发展和特点。这些器件采用波长偏移荧光剂将极紫外（EUV）氦闪烁光转换为可见光，从而将信号光传输到室温。研制并试验了三种技术途径：波长漂移光纤、复合亚克力管和膨胀聚四氟乙烯漫反射管。基于管的探测器已被用于探测磁捕获的中子。所有的技术方法在其他实验中也有实用价值，如更灵敏的测量中子电偶极矩和监测低能太阳中微子通量。
Detectors for counting low energy (less than 1 MeV ) ionizing events in liquid helium are developed and characterized. These devices employ wavelength shifting fluors to convert extreme ultraviolet (EUV) helium scintillation light to the visible, allowing transport of signal light to room temperature. Three technological approaches are developed and tested: wavelength shifting fiber, composite acrylic tube, and diffuse reflecting tube of expanded teflon. The tube-based detectors have been used to detect magnetically trapped neutrons. All of the technological approaches have utility in other experiments, such as a more sensitive measurement of the neutron electric dipole moment and the monitoring of the low-energy solar neutrino flux.
