Plastic scintillation dosimetry: optimal selection of scintillating fibers and scintillators.

Medical physics, 2005
Scintillation dosimetry is a promising avenue for evaluating dose patterns delivered by intensity-modulated radiation therapy plans or for the small fields involved in stereotactic radiosurgery. However, the increase in signal has been the goal for many authors.

How scintillating is scintillation?

2019 URSI Asia-Pacific Radio Science Conference (AP-RASC), 2019
Global Navigation Satellite Systems (GNSS), including the Global Positioning System (GPS), GLONASS and Galileo, support a wide range of civilian and military applications, and have become indispensable in precise positioning and time keeping. Ever-increasing dependence on space technologies pervades every area of our daily life like never before in ...

Polychromatic scintillation

Journal of the Optical Society of America A, 2003
A formula to compute the index of stellar scintillation detected with a finite spectral bandpass and with arbitrary aperture is derived in the limit of weak perturbations. It also applies to differential scintillation (relative fluctuations of light intensity in a pair of apertures), where the effect of finite bandpass turns out to be significant.

Scintillation and Inorganic Scintillators

2016
This chapter introduces the basic definitions and gives the minimum necessary information about the phenomenon of scintillation and the mechanisms which have to be taken into account for the development of scintillation materials. It starts with an historical brief and describes the sequence of the processes leading to scintillation in a dielectric ...

Scintillation Mechanisms in Inorganic Scintillators

2016
Details of energy transfer phenomena and scintillation mechanisms in luminescent media excited by ionizing radiation are discussed in this chapter. The sequence of relaxation of electronic excitations is described: creation of electron-hole pairs, energy transfer to emitting centers of interest and quantum efficiency of these luminescence centers.

A new scintillator for liquid scintillation counting

The International Journal of Applied Radiation and Isotopes, 1967
Abstract This report describes the results of investigations carried out with a new scintillator: 2-(4′-t-Butylphenyl)-5-(4″-biphenylyl)-1,3,4-oxdiazole (Butyl-PBD). Counting efficiencies and background counts of variously quenched toluene and dioxane systems containing Butyl-PBD have been compared with similar systems containing PPO and DM-POPOP as ...

Liquid scintillators with advanced scintillation characteristics

Instruments and Experimental Techniques, 2010
Results of studying the influence of the component composition of liquid scintillators on their scintillation properties are presented. The correlation between the energy resolution and the peak-to-valley ratio in β-ray spectra is discussed. Compositions of fire-safe scintillation systems with characteristics above the generally accepted standard are ...
