Pulse height model for deuterated 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...

New approach for calibration of pixelated scintillation detectors of intraoperative gamma cameras

Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...

Tomographic Analysis of Neutron and Gamma Pulse Shape Distributions from Liquid Scintillation Detectors at JET

Fast digitizing techniques applied to scintillation detectors

A 200 MHz 12-bit fast transient recorder card has been used for the digitization of pulses from photomultipliers coupled to organic scintillation detectors. Two modes of operation have been developed at ENEA-Frascati: a) continuous acquisition up to a maximum duration of ∼ 1.3 s corresponding to the full on-board memory (256 MSamples) of the card: in this mode, all scintillation events are reco...

Calculation of the Pulse Height Distribution Induced by Fast Neutrons in a Scintillation Detector

The probability distribution of light pulses produced in an organic scintillator by impinging fast neutrons is calculated. It is assumed that the slowing down takes place on a mixture of hydrogen and carbon atoms, and that the light produced is a non-linear function of the energy transferred to the H atoms and a linear function of the transferred energy to C atoms in each individual collision. ...
