Advanced Photon Detector R&D

How do we approach the fundamental questions on the origin of the Universe, life and consciousness? Is there anything common in the experimental technique? Surprisingly there is indeed one unified approach that is based on detection of weak light signals. It could be from the farthest distance by means of optical telescopes like Hubble Telescope, or from the highest energy phenomena at the LHC by the CMS Detector. It could be from the detectors deep underground to detect neutrino of dark matter.


The figure above is the Super Kamiokande Neutrino Observatory in Kamioka Japan. It is a gigantic water tank of which the inside wall is covered by ~11,000 of the world’s largest 20 inch diameter photomultipliers (PMT). Development of the 20 inch PMT was Arisaka’s first contribution to the physics world as a grad student at University of Tokyo while working under Professor. Toshi Koshiba back in the early 1980's. It is a perfect example of how new photon detectors can advance the science frontier in profound ways. Since that time, Arisaka and his group have been actively involved in the development of advanced photon detectors for the last three decades. In 2006, Arisaka decided to apply the new technology of advanced photon detectors to optical bio imaging, inspired by Professor Shimon Weiss's innovative work on single molecule imaging using Quantum dots.

Collaboration with Hamamatsu Photonics in Japan

Since the initial development of the 20 inch PMT, Arisaka has been closely collaborating with Hamamatsu Photonics in Japan. Hamamatsu is the leading company of advanced photon detectors, and our 30 year long collaboration has successfully resulted in the following developments and commercialization:

  • 20 inch diameter photomultiplier (used by Kamiokande and Super-Kamiokande)
  • Position sensitive photomultiplier based on Venetian blind dynode (used by FNAL-E799)
  • Low gain/High linear photomultiplier (used by FNAL-KTeV)
  • Position sensitive photomultiplier based on Metal Channel Plate (used by CDF Shower Max, MINOS etc.)
  • GaAs and GaAsP photo cathode (tried by Near Infrared Imaging and adopted by MAGIC)
  • Hybrid APD with GaAsP photo cathode (used by Leica HyD confocal microscopes)
  • 64 channel GaAsP HAPD (developed for photon-counting time correlated single molecule imaging as Weiss' Lab)
  • Radiation free photon detector, called QUPID (Quartz Photon Intensifying Detector)
  • Special bi-alkali photocathode for low temperature operation (now widely adopted by liquid argon and xenon)
  • Image Intensified CMOS camera (commercialized by Photron, installed at CNSI core facility)
