12 when a chain reaction destroyed 7,000 of the 11,000 photomultiplier
(PMT) tubes installed in the system to collect Cerenkov light for neutrino study.
These photons are detected by chemical-compound crystals, implanted in a ring around the targeted body part and connected to photomultipliers
look downward to detect events from cosmic neutrinos that have passed completely through the Earth.
Large system OEMs can now comfortably design in reliable silicon photomultipliers
and be confident of receiving sensors with high performance and uniformity, in any volume needed, at very low cost.
HV supplies lie at the heart of electron beam systems, lasers, radar modulators, projection TVs, particle accelerators, ionization chambers, mass spectrometers, photomultipliers
, advanced rotogravure printers, and even something called a "magnetohydrodynamic device for removing inclusions from molten metal.
The second stage of DUMAND, the actual instrument, will consist of 208 photomultiplier
detectors, distributed among nine strings each 330 meters long.
offer very high PDE, ultra-short response time, and extremely low power consumption, making them ideal for a variety of low light level applications such as fluorescence and molecular imaging.
Arrangements of photodetectors and photomultipliers
on the ground detect the Cherenkov radiation from the particle showers triggered by the TeV gamma rays hitting the atmosphere.
17) SiC avalanche photodiodes and photomultipliers
for ultraviolet and solar-blind light detection
(SiPMs), in particular, are an emerging and very promising technology due to their photon number resolution at room temperature, insensitivity to magnetic fields, compactness and relatively low operating voltages.
has been awarded a grant under the Department of Energy Small Business Innovation Research (DOE SBIR) program to develop large-area microchannel plates for use as an alternative to traditional photomultipliers
The use of new photosensors, the silicon photomultipliers
, in cosmic rays experiments is also addressed.
