Description
LOREA, the ninth beamline of the ALBA synchrotron radiation source, started its operation in 2021 and is dedicated to electronic structure investigation of quantum materials by means of Angle Resolved Photo-Emission Spectroscopy (ARPES).
The photon energy range of the beamline (10-1000 eV) with continuously variable polarization and resolving power of more than 10ˆ4 in the whole range allows the complete characterisation of samples. A small spot size of about 10x10 μmˆ2 and the presence of 4 electrical contacts in the sample stage enables LOREA to characterise very small samples and simple devices.
The ARPES detector is an MBS A-1 hemispherical analyzer with very high energy and angular resolution (better than 1meV and 0.1˚) and the fast Fermi surface mapping mode. It will be upgraded in 2022 with a spin detector to perform spin-resolved ARPES.
The 6-axes cryo-manipulator can reach temperatures lower than 7.5K.
The main chamber is connected to a central radial distribution chamber and, through it, to all other vessels, including chambers for in situ UHV deposition and characterization, load lock and sample storage, docking of vacuum suitcase.
This project is co-funded by the European Regional Development Fund (ERDF) within the “Framework of the Smart Growth Operative Programme 2014-2020”
