The remainder of the FALS is measured by a photodiode or a photomultiplier tube
The optimum settings of laser power and photomultiplier tube
voltage were determined in a preliminary experiment based on the AF levels of untreated sections of either normal or diseased mouse kidney and were subsequently used for all SBB-treated sections.
This gives equivalent performance to other systems using photomultiplier tubes
, and is also smaller and lighter leading to a more economic unit price.
About 7,000 of the 11,000 photomultiplier tubes
attached to the neutrino detector operated at the university's research facility in the city of Hida in Gifu Prefecture were found broken in November 2001 due to a chain reaction.
Paris, France 8/23/05 -- Photonis Holding SAS has acquired Burle Industries, a manufacturer of specialized electron tubes and electro-optic products, including photomultiplier tubes
, Channeltron mass spectrometry detectors and advanced performance detectors.
is the optic design that utilizes CCD detector technology, which is a solid-state detector rather than traditional photomultiplier tubes
were employed for both emission and reference detectors.
The LynX(TM) SiPM Module offers an attractive alternative to traditional Photomultiplier Tubes
(PMTs) for a variety of Analytical Instrumentation and Life Sciences applications including Fluorescence measurement and Flow Cytometry.
We power photomultiplier tubes
, electron multipliers, microchannel plates and more; anything that benefits from a stable and adjustable high voltage supply.
Gallium arsenide phosphide photomultiplier tubes
(GaAsP PMTs) display high light collection efficiencies over a broad spectral range.
Such flashes can be detected by putting a tank of liquid deep underground to shield it from most stray particles, then lining the tank with photomultiplier tubes
that can pick up even the faintest bursts of light.
Side-scatter and fluorescent signals are collected with photomultiplier tubes
because of their sensitivity and high gains.
