XAHRM ‐Lab First Results and πXRF First View of UFe 4 Al 8 and UFe 10 Si 2

ABSTRACT Following the installation of the Laboratory for the Characterization and Speciation of Aerosols (LCEA) in 2008, and the confirmation of High Resolution Energy Dispersive Spectrometry (HiREDS) as a much promising development for X‐ray Emission Spectrometry in general and Particle Induced X‐ray Emission (PIXE) in particular, the installation of the X‐ray Advanced HiREDS Research and Metrology Laboratory (XAHRM‐Lab) was launched in 2020 at the Campus Tecnológico e Nuclear (CTN) of IST, the University of Lisbon Engineering School, under the scope of the AHEAD2020 EU infrastructures project. Being a major upgrade to the LCEA, XAHRM‐Lab aims at being an ion beam analysis infrastructure focused mostly on new developments and metrology work. XAHRM‐Lab is designed to hold two X‐ray detectors to be used in six different analytical geometries, including PIXE induced XRF (πXRF) and in air geometry variants. In this work, XAHRM‐Lab installation status and a set of first results from πXRF and PIXE spectra of UFe 4 Al 8 and UFe 10 Si 2 crystals, taken without breaking vacuum, are presented and discussed.
