Feasibility Study of an Alcohol-Based Liquid Scintillation Detector and Its Application

Abstract

This paper proposes a new base material, a mixture of alcohol and water, for liquid scintillators. A possibility of using alcohol as a new detection solution in a particle detector is described. A liquid scintillator is widely used in various fields because of its high light yield. In addition, it is very important to develop a stable liquid scintillator for particle detectors or other medical applications. To date, there have been no previous R&D studies elsewhere for the use of alcohol in particle detectors, and no market products are available of this type. Thus, there is a room for improvement. This paper describes the brief synthesizing process of the alcohol-based liquid scintillator by varying the mixing ratio of each component that makes up the liquid scintillator. The several feasible physical and optical properties of an alcohol-based liquid scintillator were investigated and presented. Finally, as one of its applications, a range (beam-path length) measurement using an electron beam in medical physics is introduced after irradiating an alcohol-based liquid scintillator with electron beam energies of 6~12 MeV. The measurement results were compared with a Monte Carlo simulation, Novalis Tx, a phantom, and a CT image. In the near future, the new alcohol-based liquid scintillator could be used for particle detector or medical imaging applications.

Pixel Image Analysis and Its Application with an Alcohol-Based Liquid Scintillator for Particle Therapy

“…Therefore, one advantage is that the user can easily select the synthesis procedure and the chemical composition ratio for the LS. Organic, solvent-based LSs in high-energy physics used an optimized primary fluor of ~3 g/L anda secondary fluor composed of ~30 mg/L [15,16]. In our study, 2,5-diphenyloxazole (C 15 H 11 NO, PPO) was used as the primary fluor, and 1, 4-bis(2-methylstyryl) benzene (C 24 H 22 , bis-MSB) was added as the secondary fluor.…”

“…The optimized ratio of 2-ethoxyethanaol to water was 7:3. Optical and physical properties of the AbLS were described in detail elsewhere [15,16].…”

Dopant-Free, Blue-Light-Emitting, Hydrophobic Deep Eutectic Solvent and Its Application as a Liquid Scintillator

“…23 Generally, an organic scintillator uses dissolved fluorophores, both primary and secondary, for efficient light emission in the sensitive region of the photomultiplier tube (PMT), typically at wavelengths around 400−430 nm. 24 A well characterized liquid scintillator for gross photon counting is in high demand for several applications including safeguards. 25 Although seen as a scintillator of choice in the future, the toxicity and easy flammability of liquid scintillators have restricted their use.…”
