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...
متن کاملNew 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...
متن کاملSalty Water Cerenkov Detectors for Solar Neutrinos
The addition of certain solutes to a water Cerenkov detector will introduce new charge-current channels for the detection of νes. The experimental conditions necessary to exploit such signals large volumes and very low backgrounds should be reached for the first time in SuperKamiokande and SNO. I compare some of the more attractive possibilities (7Li, 11B, 35Cl) in terms of counting rate, relia...
متن کاملWater-equivalent plastic scintillation detectors for high-energy beam dosimetry: II. Properties and measurements.
The properties of a new scintillation detector system for use in dosimetry of high-energy beams in radiotherapy have been measured. The most important properties of these detectors are their hgh spatial resolution and their nearly water-equivalence. Measurements have shown that they have excellent reproducibility and stability, and a linear response versus dose-rate. It is also shown that they ...
متن کاملWater-equivalent plastic scintillation detectors for high-energy beam dosimetry: I. Physical characteristics and theoretical consideration.
A minimally perturbing plastic scintillation detector has been developed for the dosimetry of high-energy beams in radiotherapy. The detector system consists of two identical parallel sets of radiation-resistant optical fibre bundles, each connected to independent photomultiplier tubes (PMTs). One fibre bundle is connected to a miniature water equivalent plastic scintillator and so scintillatio...
