摘要:

双OZ实验的目标是使用两个相同的探测器精确测量最后一个未知的混合角θ_13,这两个探测器分别放置在离OZ反应堆堆芯较远和较近的位置。该探测器使用专门开发的10英寸光电倍增管进行反应堆中微子探测优化。我们开发了两种类型的测量系统,并在安装前对400台PMT进行了评估。这些光电倍增管满足我们的要求,其中一半已安装到远探测器在2009年。光电倍增管的特性和性能数据存储在数据库中,并将在分析和MC仿真中参考。

英文摘要:

The goal of Double Chooz experiment is a precise measurement of the last unknown mixing angle theta_13 using two identical detectors placed at far and near sites from Chooz reactor cores. The detector is optimized for reactor-neutrino detection using specially developed 10-inch PMTs. We developed two types of measurement systems and evaluated 400 PMTs before the installation. Those PMTs fulfill our requirements, and a half of those have been installed to the far detector in 2009. The character and performance data of the PMTs are stored in a database and will be referenced in analysis and MC simulation.
