A photomultiplier tube is a device used to measure very low levels of light. It’s a common tool of particle physics when trying to detect just a few photons. It turns out that running a tube at ...

In both techniques, sensitive light detectors called photomultiplier tubes are arrayed around the tank to record the ...

Photomultiplier tubes consist of an evacuated envelope with a photocathode that emits electrons when exposed to light. These electrons are accelerated by a positive electrostatic field and fall upon a ...

Solid state electronics have provided lighter weight night vision units that work better than the old-fashioned gear that used photomultiplier tubes, but there was an even older technology as [Our ...

It utilizes a technologically advanced photomultiplier tube (PMT) that amplifies ATP (adenosine triphosphate) allowing detection of lower levels of microbial and organic contamination. This is a ...

But when I unboxed my two petunias this week, they were in bad shape, with rotted leaves. And in a day, they were dead crisps ...

“It gives us a unique way of checking that our picture is consistent.” Furthermore, over 40,000 photomultiplier tubes will ...

MARION—Indiana Wesleyan University has received a $362,000 Major Research Instrumentation (MRI) grant from the National ...

The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples.

Analogous noise phenomena and dynamics also exist in other systems, including earthquakes and photomultiplier tubes as well as avalanches. In principle, quantum mechanical effects can also produce ...

Die Energie wird dann wieder als sichtbares Licht abgestrahlt und letztendlich von einem ultra-empfindlichen Silizium Photomultiplier (kurz SiPM) in einen entsprechenden Strompuls umgewandelt.
