Enhancing Signal Collection Efficiency in Liquid Scintillators via Optical Fibre End Treatments for Dosimetry Applications

This paper presents a systematic evaluation of various optical fibre end modifications aimed at enhancing signal collection from a liquid scintillator. Recognizing the significant potential of optical fibre dosimetry for long -term, high -dose ionising radiation monitoring, our study emphasizes the optimization of scintillation counting, particularly for neutron detection. By immersing the optical fibre in the liquid scintillator, we enhanced light collection and applied several end treatments, including classical cleaving, tapering, etching, and optical lens formation. Comparative analysis reveals that the choice of end treatment influences light transmission efficiency, thereby advancing the performance of scintillation -based detection systems and paving the way for improved radiation dosimetry techniques.
