Abstract
Years ahead of time, Professor Anna Giardini envisaged the possibility of "Photoionization studies of laser-excited states of simple molecules in gas-phase" as a keystone of the scientific case for the atomic and molecular beamline for the Elettra synchrotron radiation laboratory [1]. Since then the Gas Phase beamline [2] has enabled photoionization studies of isolated systems, even with very low density targets such as vapours of biomolecules, and clusters. But only recently, by pushing our capabilities to their limit, we met Prof. Giardini's challenge to run experiments on laser-excited systems [3]. As usual, Prof. Giardini has been demanding the best, and beyond! Indeed, to properly meet her original scientific demands we had to commission two new facilities at Elettra (in the framework of the FERMI Free Electron Laser (FEL) project) capable of delivering ultrafast VUV photon pulses: the Low Density Matter beamline at FERMI [4] and CITIUS [5], a state-of-the-art fs-VUV source, based on laser High Harmonic Generation on rare gases. I will present recent experiments on photoionization spectroscopy of gas phase molecular targets of increasing complexity, as well as research opportunities opened in the field of atomic, molecular and cluster physics by these novel ultrafast light sources.
