Kraków synchrotron to open a fourth beamline

Kraków synchrotron to open a fourth beamline

The installation of a straight section for an undulator marked the beginning of the construction of the PHELIX beamline in the SOLARIS National Synchrotron Radiation Centre. It will be the fourth beamline in the Kraków synchrotron, built and assembled by FMB Feinwerk- und Meßtechnik GmbH, a Germany-based company. The investment is partially funded by the Ministry of Science and Higher Education.


The undulator, which is an insertion device used in high-energy physics and the source of light from the beamline, will be transported to Kraków and installed in the storage ring in October 2018. Around that time, a lead Faraday cage will be built in the experiment hall, designed to hold the first optical elements of the beamline and protect the synchrotron staff from the detrimental effects of electromagnetic radiation. Further stages of the project include the installation of the part of the beamline located in the storage ring (January 2019) as well as building an experimental beamline with X-ray optics (February–March 2019) and an end-station (May–June 2019).

PHELIX will be a beamline using soft X-rays, the source of which will be an APPLE II undulator with permanent magnets. This type of insertion device gives the opportunity to obtain a variable polarization of light: linear polarization at any angle as well as circular and elliptical polarization. Currently, the PHELIX beamline is at an advanced stage of design. The PHELIX end-station will enable a wide range of spectroscopic and absorption studies characterised by different surface sensitivity. Besides collecting standard high-resolution spectra, it will allow, e.g. to map the band structure in three dimensions and to detect the spin in three dimensions.

The beamline’s applications include:

  • new materials for spintronics and magnetoelectronics, topological insulators,
  • thin films and multilayers systems including samples obtained in-situ,
  • surface of bulk compounds,
  • surface magnetism, spin polarized surface states,
  • chemical reactions taking place on the surface,
  • biomaterials.

The National Centre for Synchrotron Radiation functions under the auspices of the Jagiellonian University. Synchrotrons open up completely new research possibilities, allowing for obtaining better results than those from studies carried out using traditional methods. The synchrotron beamlines are currently the most versatile research tools possessed in the natural and technical sciences, such as biology, chemistry, physics, materials engineering, nanotechnology, medicine, pharmacology, geology, or crystallography.
