Characterization of OSL dosimeters used at the ELI-beamlines laser-driven accelerator facility

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 10 24 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 ca...
