An international collaboration of physicists working on a neutrino experiment in southern China announced today they have made a difficult measurement scientists have been chasing for more than a decade.

The results of the Daya Bay neutrino experiment open an important window into understanding the behavior of neutrinos, and now the race is on to determine the implications. Two American experiments, one proposed and one under construction, seem well positioned to take the next steps. See:Daya Bay experiment makes key measurement, paves way for future discoveries

PMTs convert light from particle collisions to electric charge. Since the experiment must collect the light emitted from each event, the reflectors at top and bottom of the acrylic vessels enhance gathering of light.
