Query: Monitoring Reactor Anti-Neutrinos Using a Plastic Scintillator Detector
  in a Mobile Laboratory   Technology developed for the T2K electromagnetic calorimeter has been adapted
to make a small footprint, reliable, segmented detector to characterise
anti-neutrinos emitted by nuclear reactors. The device has been developed and
demonstrated by the University of Liverpool and underwent field tests at the
Wylfa Magnox Reactor on Anglesey, UK. It was situated in a 20\,ft ISO shipping
container, above ground, roughly 60\,m from the 1.5\,\GWt\ reactor core. Based
on the design of the T2K Near Detector ECal, the device detects anti-neutrinos
through the distinctive delayed coincidence signal of inverse $\beta$-decay
interactions using extruded plastic scintillator and Hamamatsu Multi-Pixel
Photon Counters.
