Time and position distributions in large volume spherical scintillation detectors

Scintillation detectors for x-rays

Recent research in the field of phosphor and scintillator materials and related detectors is reviewed. After a historical introduction the fundamental issues are explained regarding the interaction of x-ray radiation with a solid state. Crucial parameters and characteristics important for the performance of these materials in applications, including the employed measurement methods, are describ...

Spherical-Homoscedastic Distributions Spherical-Homoscedastic Distributions: The Equivalency of Spherical and Normal Distributions in Classification

Many feature representations, as in genomics, describe directional data where all feature vectors share a common norm. In other cases, as in computer vision, a norm or variance normalization step, where all feature vectors are normalized to a common length, is generally used. These representations and pre-processing step map the original data from R to the surface of a hypersphere Sp−1. Such re...

A Time Compensator for Large Scintillation Counters*

A circuit is described which develops time-invariant pulses for large scintillation trigger counters. For a 8.56 ft long counter, a unit capable of f 22 nsec range is described; the constancy of delay of output for this unit over the full delay range is typically & 400 psec. * Work supported by the U. S. Atomic Energy Commission. (Submitted to Nucl. Instr . & Methods. ) 1 D Introduction One of ...

Inorganic scintillating materials and scintillation detectors

Scintillation materials and detectors that are used in many applications, such as medical imaging, security, oil-logging, high energy physics and non-destructive inspection, are reviewed. The fundamental physics understood today is explained, and common scintillators and scintillation detectors are introduced. The properties explained here are light yield, energy non-proportionality, emission w...
