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 0’s, especially
the cross section for neutral current 0 interactions, which are one of the dominant sources of
background to the μ! e appearance 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
