Daya Bay-Ⅱ Center Detector Simulation

Neutrino physics is a21st century particle physics and nuclear physics, astrophysics and cosmology of interdisciplinary and hot research topic. Observed neutrino oscillation model is the only phenomenon beyond the standard model, the impact is likely to open a new window of physics. Is one of the six basic mixing parameters of neutrino physics theory, determines a neutrino physics research direction, directly determines the strength of the neutrino oscillation CP violation. Daya bay reactor neutrino experiment is designed to accurately measure Angle of neutrino mixing parameters and make the sensitivity of0.01or better.Daya bay in December2006, a period start neutrino experiment, after six years of hard struggle, finally made a remarkable achievement in March2012. Daya bay-II neutrino experiment is based on daya bay neutrino, probe the volume and quality of more than a period, the number of the photomultiplier tube for more than a period, the experimental results more precise than that of the issue.Research of this paper is based on daya bay-Ⅱ center detector simulation, analysis of the experimental results. For daya bay-Ⅱ center detector uses the merits of the two models, this article does not do research. In this paper, we study daya bay-Ⅱ center detectorsimulation model of the cylinder. Research work is mainly in the center of the daya bay detector model on the basis of the second phase detector of the cylinder. There are the work:Daya bay-Ⅱ center detector at the centre of the energy scale value is1159PE/2.5Mev=463.6PE/MeV.Daya bay-Ⅱ center detector to ray energy accuracy of 6.1MeV gamma is A±η=2.08%±0.19%,to ray energy accuracy of2.2MeV gamma is A±η=3.41%±0.31%,to ray energy accuracy of1.461MeV gamma is A±η=4.16%±0.39%,to60Co precision of radioactive source of energy is A±η=3.22%±0.29%,to68Ge precision of radioactive source of energy is A±η=4.83%±0.48%.
