Description

This activity is part of the abovEF project, funded by the FIS2 program. A central element is the construction of an innovative high-resolution spectrometer operating in the far-UV region. The instrument's design depends critically on the choice of a two-dimensional detector and, in particular, on the precision with which it records the impact position of the photons. The collaborator will carry out measurements aimed at characterizing the response of a CCD detector for UV radiation in the 20–40 eV range, corresponding to the expected operating values for the abovEF instrument under development. Analysis of the detector's response serves to optimize the spectrometer's optical design. A helium plasma discharge source and a liquid nitrogen-cooled CCD, both already available, will be used. Analysis of experimental data and comparison with numerical simulation results will be an integral part of the assignment
