Directional characteristics of cylindrical scintillators

Nuclear Instruments and Methods, 1971
Abstract The general analytical solution is presented for the detection cross section, efficiency and directivity of a cylindrical scintillator irradiated by a gamma-ray source located off the axis. The calculated parameters for a cylindrical scintillator are compared with those for a cuboidal scintillator, which represents a useful approximation ...

Timing characteristics of scintillator bars

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002
Abstract The proposed Hall D detector at Jefferson Lab will have a time-of-flight detector composed of long and narrow scintillator bars. We have evaluated the time resolution of two bar prototypes in particle beams at the Institute for High Energy Physics in Protvino, Russia.

Scintillation characteristics of Cs2LiCeBr6 crystal

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2011
Abstract This work investigates the scintillation properties of Cs 2 LiCeBr 6 crystal as a new material for radiation detection. This scintillation material is grown by the vertical Bridgman method. Under X-ray excitation the sample crystal shows a broad cerium based emission band between 390 and 450 nm wavelength range.

The Energy Characteristics of a Multichannel Scintillation Spectrometer

Instruments and Experimental Techniques, 2021
A multichannel scintillation spectrometer with a thickness of 2.5X0 has been calibrated on a secondary electron beam with energies of 23−280 MeV at the Pakhra accelerator of the Lebedev Physical Institute. The relative energy resolution of the spectrometer is determined by the electron energy and the spectrometer thickness.

Characteristics of Plastic Scintillators

The Journal of Chemical Physics, 1957
Information on the light output of a group of organic solutes in polyvinyltoluene has been obtained. The primary solutes studied are p-terphenyl and 2-phenyl-5-(4-biphenylyl)-1,3,4 oxadiazole (PBD), the latter being the most efficient. Of the secondary solutes studied, 4,4′-diphenylstilbene and 2,5-dibiphenylyl oxazole (BBO) are the most efficient. The

Characteristics of scintillation detectors based on inorganic scintillators and SiPM light readout

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2013
Abstract Recently, a silicon photomultiplier (SiPM) became one of the strongest candidates for application in PET–MR or SPECT–MR dual-modality scanners. However, optimization of the scintillation detectors with SiPM light readout requires different approach than in the case of classic photomultipliers.

Decay characteristics of inorganic scintillators

Journal of Physics E: Scientific Instruments, 1978
The two-photomultiplier method of studying scintillator decay has been adapted to measure over the time range from 0.1 mu s to 3 ms. Results are given for the most commonly used inorganic scintillators with both alpha and gamma excitation. It is found that the decay is, in most cases, better described by a power law than by a series of exponentials ...

Characteristics of the abrupt scintillation boundary

Journal of Atmospheric and Terrestrial Physics, 1972
Abstract An abrupt onset of scintillation on 40-MHz beacon satellite records occurs within the invariant latitude range 36–63° along the New Zealand meridian. Equatorward boundaries of the irregular regions giving rise to the scintillation occur most often near 56° invariant. The boundaries at the lower latitudes occur mainly at night.

On Selecting the Characteristics of Filters for Scintillation Measurements

IETE Technical Review, 1990
This paper presents a detailed account on the selection of proper filters for tropospheric scintillation measurements. The effects and errors due to digital sampling of continuous signals are briefly discussed. The procedure to decide the characteristics of the filters from the basic theory of amplitude and phase variance, and spectral density ...
