Exploring the intrinsic energy resolution of liquid scintillator to approximately 1 MeV electrons
Y. Deng, X. Sun, B. Qi +22
We proposed a novel method for exploring the intrinsic energy resolution of a liquid scintillator (LAB + 2.5 g/L PPO + 3 mg/L bis-MSB) for approximately 1 MeV electrons. With the h…
Simulation of background reduction and Compton depression in low-background HPGe spectrometer at a surface laboratory
ShunLi Niu, Xiao Cai, ZhenZhong Wu +13
High-purity germanium detectors are well suited to analysis the radioactivity of samples. In order to reduce the environmental background, low-activity lead and oxygen free copper…
