Seminar: Energy and angular resolved photoion–photoelectron / Auger electron coincidence experiment at the PLEIADES beamline at the Synchrotron SOLEIL

On May 9th, 2025, at 3:00 PM, the seminar titled "Energy and angular resolved photoion–photoelectron / Auger electron coincidence experiment at the PLEIADES beamline at the Synchrotron SOLEIL" will be presented by Prof. Dr. Aleksandar R. Milosavljevic, researcher at the SOLEIL Synchrotron. The seminar will take place in Seminar Room 213, Department of Physics.

Abstract:

I will briefly present the SOLEIL synchrotron (Saint-Aubin, France), the PLEIADES beamline and give a more detailed description of the EPICEA permanent setup for photo-ion photoelectron coincident (PEPICO) spectroscopy. PLEIADES is a VUV – soft X-ray beamline, covering the photon energy range of roughly 10-1000 eV, dedicated to XPS/NEXAFS of isolated (gas-phase) species (atoms, molecules, clusters, nanoparticles, ions) and liquids (in-vacuo liquid jet spectroscopy). The EPICEA setup is one of the permanent experimental stations at PLEIADES, which was developed to perform Auger/photoelectron photoion photoion coincident (PEPIPICO/AEPIPICO) measurements [1-3]. It is based on a double toroidal electron analyser (DTA) and a time of flight (TOF) ion detector with 3D focusing capabilities. The detected electron makes a start trigger for the ion TOF. I will give some examples dedicated to the investigation of state-selected dissociation of small organic molecules.
