We request 4 days on VESUVIO to benchmark quantitatively the performance of the spectrometer, and to start the creation of an ad-hoc database for instrument-model validation.The sample considered for measurements on VESUVIO will be zirconium hydride, a standard both on TOSCA and VESUVIO. The data will also be used to perform the validation and preparation of TOSCA and VESUVIO virtual models and virtual samples. The data will be manipulated and treated by chemometric techniques, starting with Principal Component Analysis (PCA).
