Always been a leader in Photonic Device performance, Hamamatsu has now developed a PMT with a quantum efficiency (QE) of 45%. In all kinds of high-precision light measurements, high sensitivity and high QE are absolutely essential elements in extending detection limits and unlocking new knowledge. For Hamamatsu, however, this 45% QE is just one more step along the road. Aiming for the peak of PMT performance will open up all kinds of new possibilities.

An eighth of the machine – sector 7-8 – is now fully interconnected and cool-down has begun (p5), and the production of main quadrupoles and short straight sections is now complete (pp 25 and 27). CERN Courier January/February 20 07 CCJanFebContents.indd 3 16/1/07 15:53:08 Showtime! Picture this.... 2 Years of preparation. Writing a proposal, feasibility reports, getting the funds and fi nding that perfect spot for your fi eld trial. Some parts are more diffi cult to get than others. The spectroscopy part is easy; you choose the custom confi gured Ocean Optics USB4000-FL for optimal sensitivity and the direct attached light source USB-LS-450. Together with the special probe you got from Ocean Optics, you have a complete mobile fl uorescence measurement solution. Everything connects through USB2.0 to your laptop, storing your precious data... Now you have performed your measurements and got terrifi c results! What are you going to do? Shout it from the rooftops, tell your friends, write your paper for the upcoming conference. And of course illustrate everything with some high-quality pictures. Then, it’s a small step to send your pictures to us and earn even more credits! This year’s grand prize in the Ocean Optics European photochallenge is an ASUS tablet PC . What’s next: 1. Mail your favorite application picture, together with a short description, to [email protected] 2. Receive one of the popular Ocean Optics t-shirts or caps 3. WIN the ASUS tablet PC with Windows XP (tablet PC edition) and the latest version of SpectraSuite installed +31 26 319 0500 Please note that the pictures and the description submitted will become [email protected] property of Ocean Optics B.V. and can be used for marketing purposes.
