Study of J/psi->eta phi pi+pi- at BESIII
M. Ablikim, M. N. Achasov, X. C. Ai +402
Based on a sample of events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay . The…
Evidence for at center-of-mass energies from 4.009 to 4.360 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +405
Using data samples collected at center-of-mass energies of = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a s…
p/ response of single layer THGEM detector in Ar/3%iCH
Daojin Hong, Bo xiang Yu, Hongbang Liu +12
In this work, we study the response of single layer Thick GEM (THGEM) detector to p/ at E3 line of Beijing Test Beam Facility. In our experiment, the drift gap of THGEM Dete…
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…
Aging research of the LAB-based liquid scintillator in stainless steel container
Hai-tao Chen, Bo-xiang Yu, Qing Shan +13
Stainless steel is the material used for the storage vessels and piping systems of LAB-based liquid scintillator in JUNO experiment. Aging is recognized as one of the main degradat…
Simulation and performance study of the ceramic THGEM
Jia-Qing Yan, Yu-Guang Xie, Tao Hu +6
The THGEMs based on ceramic substrate were developed successfully for neutron and single photon detection. The influences on thermal neutron scattering and the internal radioactivi…
