Description
The Near Detector (ND280) of the T2K experiment is instrumented with an almost hermetic segmented Pb-scintillator electromagnetic calorimeter (ECAL), the main purpose of which is the measurement of photons, electrons and other particles escaping the inner detectors. Light produced in scintillator bars is collected by wavelength-shifting fibers and converted into electronic pulses by multi-pixel photon counters (MPPCs). We present here details of the ECAL's design and performance since the beginning of operations at the end of 2009.
