Description
Extreme Light Infrastructure - Nuclear Physics (ELI-NP) represents a world-class, state-of-the-art research infrastructure specifically designed to push the boundaries of photonuclear physics. The facility is equipped with advanced systems for the generation of high-energy particle fields, complemented by sophisticated monitoring instrumentation tailored for the precise detection and characterization of harsh radiation environments. At the core of its experimental capabilities, ELI-NP operates a High Power Laser System (HPLS) with peak powers reaching up to 10 PW. This system produces intense pulsed fields through the interaction between the laser beams and various experimental targets.
Radiation monitoring within the facility is systematically conducted using two distinct techniques: active and passive. The active detection equipment used for characterization of photon pulsed fields is the NAUSICAA ionization chamber. The passive monitoring component employs BeOSL (Beryllium Optically-Stimulated Luminescence) dosimeters, which ensure robust measurements by remaining independent of the photon field's pulsed characteristics.
This comprehensive study aims to evaluate and compare the monthly dosimetric data obtained over time at key points surrounding the experimental bunkers. The present work includes correlations with various experimental campaigns, accounting for fluctuations in laser beam power, target materials and shielding configurations. Furthermore, this scientific work focuses on a comparative analysis between the values recorded by the NAUSICAA active detectors and the data provided by the BeOSL passive dosimeters to ensure cross-validation and monitoring accuracy. The data obtained supports the radiation protection approach and provides input for different radioprotection measures implemented to maintain dose constraints.
