For example, in a scintillation detector, incident radiation excites a fluorescent material that de-excites by emitting photons of light.
12.
Thus, better scintillator design is also in the foreground and has been the topic of pursuit ever since the invention of scintillation detectors.
13.
Each surface detector has an assembled weight of 250 kg and consists of a power supply, two layers of scintillation detectors and electronics.
14.
Each scintillation detector layer is made of extruded plastic scintillator that is 1.2 cm thick and has an area of 3m 2.
15.
Li 2 MoO 4 crystals have been found applicable for cryogenic phonon-scintillation detectors, which are used to investigate some rare nuclear processes.
16.
Scintillation detectors were invented in 1903 by Crookes but were not very efficient until the PMT ( photomultiplier tube ) was developed by Curran and Baker in 1944.
17.
"Radiation-based Gauge " : Radiation is passed from a source, through the fluid of interest, and into a scintillation detector, or counter.
18.
Low efficiency was the result, and germanium detector efficiency is still often quoted in relative terms to a " standard " 33 x 33 NaI ( Tl ) scintillation detector.
19.
The drift chambers used in the experiment originate from the DELPHI-experiment at CERN . Additionally the limited streamer tubes and plastic scintillation detectors are part of the measurement stations.
20.
Semiconductor detectors, also called solid-state detectors, are fundamentally different from scintillation detectors : They rely on detection of the charge carriers ( electrons and holes ) generated in semiconductors by energy deposited by gamma ray photons.
