The first pulse from the photocathode is very small and is amplified in 10 stages by a series of dynodes to get a large pulse. Nuclear physics began employing scintillation counters again in the late 1940’s, when high-gain multistage photomultipliers capable of detecting extremely weak flashes of light came into use for the detection of scintillations. A description of the principle of operation of a scintillation counter follows. THE SCINTILLATION COUNTER PHYSICS 359E INTRODUCTION The development of detectors for both counting and measuring the energy of particles and photons has played an important role in the evolution of nuclear physics. In this experiment, you will be introduced to one such detector - the scintillation counter - which is particularly suitable for A scintillation counter measures ionizing radiation. A scintillation counter apparatus consists of a scintillator, a photo-multiplier tube (PMT), an amplifier, and a multichannel analyzer (Fig. 1).

Scintillates are one of the oldest types of radiation detector because measurements could be made with photographic film. The basic principle is the same for every scintillation-type detector: when radiation strikes the scintillator it causes it to give off photons of visible light (that’s the scintillation part). A scintillation counter or scintillation detector is a radiation detector which uses the effect known as scintillation.

8 Feb 2017 “Scintillation is a luminescence induced by ionizing radiation in transparent dielectric media.” Taken from: Inorganic Scintillators for Detector
In scintillation detectors the material of the detector is excited to luminescence ( emission of visible or near-visible light photons) by the absorbed photons or
A scintillation detector or scintillation counter is obtained when a scintillator is coupled to an electronic light sensor
The scintillation occurs when scintillator electrons, excited by the energy of the photon, return to their ground state.

Get Grammarly. www.grammarly.com. Chemiluminescence can be overcome by storing samples for sometime before counting, to permit the chemiluminescence to decay. Many contemporaneous instruments are able to detect chemiluminescence and substract it or flag it on the printout.
A scintillation counter is made up of a sensitive photodetector (usually a photomultiplier tube), a charge-coupled device camera (CCD) which converts light to electric signal and a scintillator which generates photons in response to incident radiation.
