Description
Optical fibre-based detectors offer unique opportunities for radiation measurement at accelerators, including medical-based applications, combining small size, flexibility, real-time response, and immunity to electromagnetic interference. This presentation focuses on the development and application of optical fibre sensors, including scintillating fibres and fibre Bragg gratings (FBGs), for dosimetry, beam monitoring, alignment, and characterization of accelerator beams used in radiotherapy and medical isotope production. In proton therapy and FLASH radiotherapy, fibre-based systems are being investigated for high-resolution, minimally perturbing measurements of dose and beam parameters, including the contribution of secondary radiation. FBG sensors are also being developed for monitoring temperature and pressure in isotope production targets, providing valuable information for understanding and optimizing target performance under high-power irradiation. This work brings together accelerator physics, detector development, medical physics, and radiation effects to establish robust optical fibre technologies for next-generation accelerator-based medical applications.
