ADRESS - X03MA: Advanced Resonant Spectroscopies

Adress Beamline 02.jpg

The ADvanced RESonant Spectroscopies (ADRESS) beamline installed in the X03MA straight section of SLS is a high-performance soft-X-ray undulator beamline operating in the energy range from 300 eV to 1.6 keV. It hosts two endstations, for Angle-Resolved Photoelectron Emission (ARPES) and Resonant Inelastic X-ray Scattering (RIXS). The scientific activity at the beamline is focused on correlated systems, topological materials, complex oxides, semiconductors and their nanostructures.

Energy range 300 - 1600 eV
Polarization circular and 0-180o variable linear polarization
Resolving power E/Δ E (1 keV) up to 33'000
Flux on sample (1 keV) >1013 ph/s/0.01%BW/400 mA
End stations Angle-Resolved Photoelectron Spectroscopy (ARPES); Resonant Inelastic X-ray Scattering (RIXS)
Spot size on sample 10 x 74 µm2 (ARPES); 4 x 52 µm2 (RIXS)

A detailed description of the ADRESS beamline can be found in J. Synchrotron Rad. 17 (2010) 631 and one of the recent presentations.

Weyl spin-momentum locking in a chiral topological semimetal

Spin–orbit coupling in noncentrosymmetric crystals leads to spin–momentum locking – a directional relationship between an electron’s spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin–momentum locking has been studied for decades, while its counterpart, isotropic parallel Weyl spin–momentum locking has remained elusive in experiments. Theory predicts ...
