深地下中微子实验远探测器的35吨原型是一个单相液氩时间投影室，带有一个集成的光子探测器系统，所有这些都位于一个薄膜低温恒温器内。该探测器在2016年2月1日至2016年3月12日期间拍摄了六周的宇宙射线数据。用这些数据检查光子探测系统的性能。安装的光子探测器被证明可以测量宇宙射线μ子的到达时间，分辨率优于32 ns，受触发系统的定时限制。使用紧密间隔的校准脉冲的定时分辨率的测量产生了在6个光电子的水平的脉冲的15纳秒的分辨率。观测到宇宙线μ子的闪烁光随距离的增加而衰减，特征长度为155 ± 28 cm。
The 35-ton prototype for the Deep Underground Neutrino Experiment far detector was a single-phase liquid argon time projection chamber with an integrated photon detector system, all situated inside a membrane cryostat. The detector took cosmic-ray data for six weeks during the period of February 1, 2016 to March 12, 2016. The performance of the photon detection system was checked with these data. An installed photon detector was demonstrated to measure the arrival times of cosmic-ray muons with a resolution better than 32 ns, limited by the timing of the trigger system. A measurement of the timing resolution using closely-spaced calibration pulses yielded a resolution of 15 ns for pulses at a level of 6 photo-electrons. Scintillation light from cosmic-ray muons was observed to be attenuated with increasing distance with a characteristic length of 155 ± 28 cm.
