双中微子实验（英语：Double Neutrino Experiment）是一个测量最后一个未知中微子混合角θ13的反应堆中微子实验。“双赫兹”实验使用两个相同的探测器，分别放置在远离和靠近赫兹反应堆堆芯的地方。该探测器采用390低背景和高性能10英寸。光电倍增管（PMT）用于检测来自钆负载液体闪烁体的闪烁光。为了测试和表征光电倍增管和调整操作参数，我们开发了两种类型的光电倍增管测试系统和评估400光电倍增管安装前。这些光电倍增管符合我们的要求，其中一半已于2009年安装在远探测器上，自2011年以来已成功获取物理数据。
The Double Chooz is a reactor neutrino experiment which measures the last unknown neutrino mixing angle θ13. The Double Chooz experiment uses two identical detectors placed at sites far and near from Chooz reactor cores. The detector uses 390 low-background and high performance 10-in. Photo-Multiplier Tubes (PMTs) to detect scintillation light from gadolinium loaded liquid scintillator. In order to test and characterize the PMTs and to tune operation parameter, we developed two types of PMT test system and evaluated 400PMTs before installation. Those PMTs fulfilled our requirements and half of them were installed in the far detector in 2009 and physics data have been successfully taken since 2011.
