The BACH beamline: recent results and future prospects

Abstract
The BACH beamline (Beamline for Advanced diCHroism) is an undulator beamline of the Istituto Officina dei Materiali-Consiglio Nazionale delle Ricerche, which operates at Elettra, in close collaboration with Sincrotrone Trieste S.C.p.A. The beamline offers a multi-spectroscopy technique approach for the investigation of the electronic, chemical, structural, magnetic and dynamical properties of solid surfaces, interfaces, thin films and solid samples in the UV-soft x-ray photon energy range (35-1600 eV) with selectable light polarization (linear horizontal and vertical, circular), high resolving power (20000-6000) and also time resolution (70 psec). A brief overview of the recent results and upgrades of the beamline will be presented, focusing in particular on the very first results of the new VG-Scienta R3000 analyser for fast photoemission, photoelectron diffraction and angle-resolved photoemission from the UV to the soft X-rays, the installation of the new UHV ±6 Tesla 1.7 K cryomagnet endstation for x-ray magnetic circular/linear dichroism (XMCD/XMLD) and time-resolved spectroscopy, the new project for the study of molecules of biological interest in a liquid environment by x-ray-emission and the first results of the new pump-probe x-ray absorption endstation which has been recently commissioned and it is now open to users.
