U41-PEAXIS
PEAXIS - Combined RIXS and XPS
U41-PEAXIS beamline is one of the highest flux beamlines at BESSY II. It provides highly focused soft X-rays, thanks to the ellipsoidal refocusing mirror. The beamline is connected to a fixed endstation PEAXIS that is dedicated to studies of angle-resolved RIXS (Resonant Inelastic X-ray Scattering) and PES (PhotoElectron Spectroscopy) on solids.
