PHELIX – A new soft X-ray spectroscopy beamline at SOLARIS synchrotron

Abstract

PHELIX is a new beamline at National Synchrotron Radiation Centre SOLARIS in Kraków using soft X-rays. The source of radiation is an Elliptically Polarizing Undulator APPLE II type with permanent magnets producing a variable polarization of light. The maximum size of the excited area on the sample will be smaller than 100 µm × 100 µm with the resolving power (RP) of at least 10000 over the entire energy range (available range 50–1500 eV) and for all polarizations. The PHELIX end-station enables a wide range of spectroscopic methods including angle integrated and angle resolved photoemission, spin resolved photoemission and x-ray absorption studies under UHV conditions. The VLEED spin detector allows to determine all three components of photoelectron spin. The beamline is perfectly suited for investigations of new electronic materials, topological insulators, thin films and multilayers systems, surface of bulk compounds, surface magnetism, spin polarized surface states, biomaterials, etc.
