Description: |
AbstractSince spring 2019 an experimental setup consisting of an electron spectrometer and an ion time-of-flight mass spectrometer for diluted samples has been available for users at the FinEstBeAMS beamline of the MAX IV Laboratory in Lund, Sweden. The setup enables users to study the interaction of atoms, molecules, (molecular) microclusters and nanoparticles with short-wavelength (vacuum ultraviolet and X-ray) synchrotron radiation and to follow the electron and nuclear dynamics induced by this interaction. Test measurements of N₂ and thiophene (C₄H₄S) molecules have demonstrated that the setup can be used for many-particle coincidence spectroscopy. The measurements of the Ar 3p photoelectron spectra by linear horizontal and vertical polarization show that angle-resolved experiments can also be performed. The possibility to compare the electron spectroscopic results of diluted samples with solid targets in the case of CO₂O₃ and Fe₂O₃ at the Co and Fe L2,3-absorption edges in the same experimental session is also demonstrated. Because the photon energy range of the FinEstBeAMS beamline extends from 4.4 eV up to 1000 eV, electron, ion and coincidence spectroscopy studies can be executed in a very broad photon energy range. see all

Construction of the FinEstBeAMS beamline was funded primarily by the European Union through the European Regional Development Fund (project ‘Estonian beamline toMAX IV synchrotron’) and by the Academy of Finland through the Finnish Research Infrastructure funding calls(FIRI2010, FIRI2013, FIRI2014). From these, FIRI2010 and FIRI2013 calls provided the main funding for the GPES endstation. The research team from University of Tartu gratefully acknowledges ERDF funding in Estonia granted to the Center of Excellence TK141 Advanced materials and high-technology devices for sustainable energetics, sensoric sand nanoelectronics (project No. 2014-2020.4.01.15-0011). |
