Characterization of the UV emission from a discharge source in a helium atmosphere using a CCD detector - 2026_IDR_DFIS_18

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description This activity is part of the abovEF project, funded by the FIS2 program. A key component is the development of an innovative, high-resolution spectrometer operating in the extreme ultraviolet (EUV) range. Part of this instrumentation will be used to measure angle-resolved photoemission spectra of the valence states in materials, allowing for the determination of the band dispersion of electronic states. Such measurements require a light source in the extreme ultraviolet (20–40 eV). The collaborator will be tasked with characterizing the emission spectrum of a UV lamp currently available at the abovEF laboratory, specifically to determine the ratio between the emission at 21.4 eV (from neutral helium) and the emission at approximately 41 eV (from singly ionized helium). This measurement will be performed using a reflection diffraction grating and a two-dimensional silicon-based CCD detector.
