PHELIX beamline – undulator installation and hutch construction

The PHELIX beamline construction continues. In October 2018 the light source for the beamline – an undulator – was installed in the storage ring. In November construction of the an optical hutch ended.

The hutch will protect people from radiation hazards. In the near future it will house the first optical components of the beamline.
The next planned steps are the installation of the front-end, i.e. the part of the beamline situated in the storage ring tunnel after the source (January 2019), the installation of the beamline with optical components for X-rays (February-March 2019) and the installation of the end-station (May-June 2019).

The PHELIX beamline will use soft X-rays. Its end station will enable a wide range of spectroscopic and absorption studies characterized by different surface sensitivity. In addition to collecting standard high-resolution spectra, it will allow, for example, to map the band structure in three dimensions and to detect electron spin in three dimensions. Users will, therefore, be able to conduct research on new materials, thin films and multilayers systems, catalysts and biomaterials, surface of bulk compounds, spin polarized surface states, as well as chemical reactions taking place on the surface.

HZB builds undulator for SESAME in Jordan

The Helmholtz-Zentrum Berlin is building an APPLE II undulator for the SESAME synchrotron light source in Jordan. The undulator will be used at the Helmholtz SESAME beamline (HESEB) that will be set up there by five Helmholtz Centres. The Helmholtz Association is investing 3.5 million euros in this project coordinated by DESY.
SESAME stands for “Synchrotron Light for Experimental Science and Applications in the Middle East” and provides brilliant X-ray light for research purposes. The third-generation synchrotron radiation source became operational in 2017. Egypt, Iran, Israel, Jordan, Pakistan, the Palestinian Authority, Turkey, and Cyprus are cooperating on this unique project to provide scientists from the Middle East with access to one of the most versatile tools for research.

New beamline for soft x-rays

Thus far, SESAME has four beamlines and will now receive a fifth meant to generate “soft” X-ray light in the energy range between 70 eV and 1800 eV. This X-ray light is particularly suitable for investigating surfaces and interfaces of various materials, for observing certain chemical and electronic processes, and for non-destructive analysis of cultural artefacts. The new beamline will be constructed as the Helmholtz SESAME Beamline (HESEB) by the Helmholtz Centres DESY (coordinating Centre), Forschungszentrum Jülich, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Helmholtz-Zentrum Berlin (HZB) as well as the Karlsruhe Institute of Technology (KIT).
