π-零探测器（Pi-zero detector，PADD）是东海-神冈（Tokai-to-Kamioka，T2 K）长基线中微子实验的离轴近探测器的子探测器之一。PSDD的主要目标是测量产生π0的中微子相互作用的相关截面，特别是中性流π 0相互作用的截面，这是T2 K中νμ→ν出现信号的主要背景来源之一。该探测器由塑料闪烁体层与水袋和黄铜片或铅片交替组成，是首批大规模使用多像素光子计数器（MPPC）的探测器之一。
The pi–zero detector (PØD) is one of the subdetectors that makes up the off-axis near detector for the Tokai-to-Kamioka (T2K) long baseline neutrino experiment. The primary goal for the PØD is to measure the relevant cross-sections for neutrino interactions that generate π0's, especially the cross-section for neutral current π0interactions, which are one of the dominant sources of background to the νμ→νeappearance signal in T2K. The PØD is composed of layers of plastic scintillator alternating with water bags and brass sheets or lead sheets and is one of the first detectors to use Multi-Pixel Photon Counters (MPPCs) on a large scale.
