Popis: The Extreme Light Infrastructure (ELI) Beamlines laser-driven accelerator facility is set to operate the most intense non-military laser system in the world, with ultra-high power up to 10 PW, concentrated plasma intensities of up to 1024 W cm−2, and ultra-short laser pulses of the order of few femtoseconds. A robust and redundant radiation monitoring system is in place to minimise risks to personnel and general public. Beryllium oxide optically stimulated luminescence (BeO-OSL) detectors are used to monitor radiation levels in the experimental building and surrounding grounds. In fact, in recent years, BeO-OSL have become an increasingly more popular choice for personal and environmental dosimetry. At ELI Beamlines, an exhaustive and thorough characterization process of the BeO-OSLs is in place. Dosimeter responses are studied as a function of delivered air kerma and photon energies. Calibration curves are calculated. Results from the latest calibration campaign are presented.
