Range measurement and fluorescence imaging analysis using electron beams with new liquid scintillator based on alcohol.

This paper proposes a new base material, a mixture of alcohol and water, for liquid scintillators. To date, there are no previous R&D studies for particle detectors with alcohol. In this study, 2-ethoxyethanol, which has a higher density than ethanol, was used to make an equivalent substance to the human body, namely, the skin or epidermis. This paper describes the brief synthesizing process of the alcohol-based liquid scintillator that was investigated and presents some of the feasible results. As one of its applications, a range (beam-path-length) measurement using an electron beam in medical physics is also described. Then, Monte Carlo simulation was performed for comparison with several other measurement results in medical physics. One of the intriguing results is that liquid scintillator component analysis can be performed through the pixel information stored in a mobile digital camera. Through the emission spectra of light, the component of the wavelength converting substances dissolved in the liquid scintillator can be known in the visible region without opening the sealed liquid scintillator. In the near future, the new alcohol-based liquid scintillator currently developed could be used for particle detector or medical imaging applications. [ABSTRACT FROM AUTHOR]
