Abstract

The Daya Bay Reactor Neutrino Experiment is designed to measure the neutrino mixing angle theta13 to world-leading precision. The experiment deploys identical antineutrino detectors at distances of 400-1900m from six reactors in Daya Bay, China. Each detector incorporates two general-purpose monitoring cameras to ensure their safe construction, transportation and operation. The cameras must meet usage goals while satisfying stringent constraints on radioactivity, materials compatibility, interference and reliability. This article describes the system design, integration, operation and performance.

    • The whole thing did in fact get written up here, though it doesn't talk much about the PMTs' IR sensitivity: https://arxiv.org/abs/1204.3500 The money plots for this discussion are Figure 7 ("this will totally work!") and Figure 9 ("this totally doesn't work!").
