New Measurement of Antineutrino Oscillation with the Full Detector Configuration at Daya Bay
(PHYSICAL REVIEW LETTERS, 2015-05)
We report a new measurement of electron antineutrino disappearance using the fully-constructed Daya Bay Reactor Neutrino Experiment. The final two of eight antineutrino detectors were installed in the summer of 2012. Including ...

Radiometric assessment of natural radioactivity levels around Mrima Hill, Kenya
(International Journal of the Physical Sciences, 2011-07)
Mrima Hill, located in the South coast of Kenya is known for high natural background radiation, due to the presence of radiogenic heavy minerals such as monazites and carbonatites. The activity concentration of 238U, 232Th ...
Reproducibility of (n,γ) gamma ray spectrum in Pb under different ENDF/B releases
(Elsevier, 2016-02)
Radiative capture reactions are of interest in shielding design and other fundamental research. In this study the reproducibility of (n,γ) reactions in Pb when cross-section data from different ENDF/B releases are used in ...
Design and optimization of HPLWR high pressure Turbine gamma ray shield
(Nuclear Engineering and Design; Elsevier, 2015-04)
This work proposes the optimum gamma ray shield thickness around the HPLWR high pressure turbine for different occupancy periods in the turbine building. Monte Carlo method was employed in the design process and only ...
Developments of oil-free Bakelite resistive plate chambers for particle physics experiments
(Journal of Instrumentation; IOP Publishing, 2014-07)
In this paper, we sumarized a Bakelite Resistive Plate Chamber (RPC) with non-oil surface treatment. This type of RPC has been installed and run smoothly in BESIII Muon identification system and Daya Bay cosmic Muon veto ...
