The ELI-NP (Extreme Light Infrastructure - Nuclear Physics) research facility is approaching full operational status. Last year, the commissioning of the 1 PW experimental area has been successfully performed with a TNSA experiment on proton acceleration. In this experiment, the laser beam was focused with a peak intensity of the order of Io > 10^21 Wcm^-2, and interacted with solid targets of various thicknesses and materials. A wide parametric scan was undertaken by shooting on different target materials and thicknesses ranging from hundreds of nm to micrometers, in a configuration without and with a plasma mirror. A wide range of laser and plasma diagnostics were deployed to characterize the laser beam and the by-products of the interaction on a shot-to-shot base. The EMP measurements conducted in parallel allowed a more accurate estimation of the EMP to be generated in high-power femtosecond laser-matter experiments envisaged at this facility, in correlation with the limits of exposure for electronic equipment and personnel. The important approaches, which are considered in the design of experimental instruments, in order to obtain and maintain the overall integrity of electromagnetic shield, will be pointed out. The challenges and different technical implemented solutions will be reported. Other solutions that are under implementation or considered for future experiments will be also discussed.
