Abstract Solar, terrestrial, and supernova neutrino experiments are subject to muon-induced radioactive background. The China Jinping Underground Laboratory (CJPL), with its unique advantage of a 2400 m rock coverage long distance from nuclear power plants, is ideal for MeV-scale experiments. Using 1-ton prototype detector the Neutrino Experiment (JNE), we detected 343 high-energy cosmic-ray muons (7.86 3.97) neutrons an 820.28-day dataset at first phase CJPL (CJPL-I). Based on neutrons,...
Photomultiplier tube (PMT) voltage waveforms are the raw data of many neutrino and dark matter experiments. Waveform analysis is cornerstone processing. We evaluate performance all waveform algorithms known to us find fast stochastic matching pursuit best in accuracy. Significant time (up 2 times) energy 1.07 resolution boosts attainable with pursuit, approaching theoretical limits. Other methods also outperform traditional threshold crossing approach resolution.
The China Jinping underground Laboratory (CJPL) is an excellent location for studying solar, terrestrial, and supernova neutrinos due to its 2400-meter vertical rock overburden. Its unparalleled depth gives opportunity investigate the cosmic-ray muons with exceptionally high average energy at $\sim360$ GeV. This paper details a study of muon-related backgrounds based on 1178 days data collected by 1-ton prototype neutrino detector used Neutrino Experiment (JNE) since 2017. apparent effects...
