AIDA-2020: Advanced European Infrastructures for Detectors at Accelerators
The AIDA-2020 project brings together the leading European infrastructures and academic institutions in detector development for particle physics, comprising more than 10,000 scientists across 24 countries. Brunel’s contribution to AIDA-2020 has been the development of a portable test-bench to enable the real-time measurement of radiation-induced absorption in scintillating and wavelength-shifting fibres.The test-bench has been designed to be used in a range of facilities, such as cobalt irradiators or high-intensity test beam facilities, the test fibres being illuminated using a combined deuterium and halogen light source focussed onto the end of the fibre. The light transmitted by the fibre is collected and measured as a function of wavelength with a linear charge-coupled device spectrometer, the impact of any radiation damage caused being visible in the resulting optical spectra.
