Pulse shape simulation for the reduced charge collection layer in p-type high-purity germanium detectors
P. Zhang, W. Dai, Q. Zhang +8
-type high-purity germanium (HPGe) detectors are widely used across many scientific domains, and current data analysis methods have served well in many use cases. However, appli…
Measurement of cosmic-ray muon flux at CJPL-II
P. Zhang, H. Ma, W. Dai +5
In China Jinping Underground Laboratory (CJPL), the deepest and largest underground laboratory globally, the cosmic-ray muon flux is significantly reduced due to the substantial sh…
In-situ environmental radiation background measurement in the second phase of CJPL
P. Zhang, Z. Zeng, J. Cheng +1
China Jinping Underground Laboratory (CJPL), the deepest and largest underground laboratory worldwide, provides a low radiation background environment, which is necessary to fronti…
Evaluation of cosmogenic Ge-68 background in a high purity germanium detector via a time series fitting method
W. H. Dai, J. K. Chen, H. Ma +4
Ge-68 is a cosmogenic isotope in germanium with a half-life of 270.9 days.Ge-68 and its decay daughter Ga-68 contribute considerable background with energy up to 3 MeV to low backg…
