LightLink® – Advances in Detector Technology based on Plastic Scintillators for α, β and γ Radiation

Plastic scintillators coupled with photomultipliertubes (PMT), have served as reliable large-area detectors for α and β radiation as well as large-volume γ detectors for many years. This contribution summarizes conventional plastic scintillation detector technologies and explores the recent strides made in detector technology through the integration of Single-Photon Avalanche Diodes (SPAD) specifically Silicon Photomultipliers (SiPM). The utilization of SiPMs brings forth a multitude of advantages over traditional detectors, ranging from reduced size and power requirements to increased robustness. This paper provides an overview of the technical aspects of these advancements, elucidating the principles behind the so-called LightLink®, SiPM-based plastic scintillator detectors and their unique features.

The discussion encompasses the practical implications of these advances, exploring their impact on the development of innovative products for detection of ionizing radiation. Applications of LightLink®-based plastic scintillator detectors in diverse fields, including handheld detectors and contamination monitors, will be elucidated, showcasing the versatility and efficacy of this evolving technology. The aim of this contribution is to provide an overview of the recent developments in plastic scintillator detector technology, emphasizing the pivotal role played by LightLink® detectors and offering insights into their potential future applications.
