Abstract

Abstract: We have designed a local trigger board for the Daya Bay reactor neutrino experiment, which is aimed to measure the neutrino mixing angle sin2 2θ 13 with a precision down to 1% level. The local trigger board processes both the total number of coincident photomultiplier tube (PMT) hits and the PMT energy sum to make trigger decisions. With this design, a high trigger probability is achieved to meet the system requirement. The design of the local trigger board is presented. [Copyright &y& Elsevier]

Abstract

Abstract: The Daya Bay reactor neutrino experiment is designed to precisely determine the neutrino mixing angle . An innovative design of the Daya Bay antineutrino detector will use optical reflective panels at the top and the bottom of the detector cylinder. This design has been tested using a prototype detector constructed at the Institute of High Energy Physics (IHEP), Beijing. A maximum likelihood event reconstruction method has been developed and tested for such a reflective prototype detector. [ABSTRACT FROM AUTHOR]
