Investigations of a Novel HyperscintTM Plastic Scintillator Detector and Hyperspectral Analysis Approach in a 74 MeV Proton Beam

A novel plastic scintillator and spectral analysis approach (Hyperscint™) was investigated in a 74 MeV proton beam for stem effect, dose and dose rate response, and suitability to provide a Cerenkov-free reference spectrum for use in MV x-ray dose calibrations.

On the nature of the light produced within PMMA optical light guides in scintillation fiber-optic dosimetry

The goal of this study was to evaluate the nature of the stem effect light produced within an optical fiber, to quantify its composition, and to evaluate the efficiency of the chromatic technique to remove the stem effect.

Development of a novel multi-point plastic scintillation detector with a single optical transmission line for radiation dose measurement

The goal of this study was to develop a novel multi-point plastic scintillation detector (mPSD) capable of measuring the dose accurately at multiple positions simultaneously using a single optical transmission line.

Review of plastic and liquid scintillation dosimetry for photon, electron, and proton therapy

While scintillation dosimetry has been around for decades, the need for a dosimeter tailored to the reality of modern radiation therapy-in particular a real-time, water-equivalent, energy-independent dosimeter with high spatial resolution-has generated renewed interest in scintillators over the last 10 years.

Water-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.

Water-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.

A method to correct for temperature dependence and measure simultaneously dose and temperature using a plastic scintillation detector

Plastic scintillation detectors (PSDs) work well for radiation dosimetry. However, they show some temperature dependence, and a priori knowledge of the temperature surrounding the PSD is required to correct for this dependence.
