Super-Kamiokande Experiment

ATM Ethernet Daughterboard

The Super-Kamiokande experiment is a large underground neutrino detector in Japan. 15,000 photomultiplier tubes are mounted in a large tank of water in an underground mine. The tubes measure tiny flashes of Cherenkov light given off by the passage of sub-atomic particles including muons and neutrinos.

The EDF built about 500 Ethernet readout cards which are used to transmit data from the detector to a bank of computers which identify interesting events for further analysis.

The Super-Kamiokande experiment is a large underground neutrino detector in Japan. 15,000 photomultiplier tubes are mounted in a large tank of water in an underground mine. The tubes measure tiny flashes of Cherenkov light given off by the passage of sub-atomic particles including muons and neutrinos.

The main detector is surrounded by an outer "veto" region which identifies and rejects data from particle interactions occurring in the surrounding rock, rather than interactions in the main portion of the detector, which are the most interesting from a physics standpoint.

The EDF designed and built about 100 of these charge-to-time converter (QTC) modules which process data from the veto region.
