Investigating polarised neutron relfectometry. Depositing multilayers using sophisticated DC-magnetron
sputtering systems. Analysing them using XRD, XRR, XPS, EDX, SEM, TEM,
MOKE, SQUID and ultimately Neutron Reflectivity and Diffraction.

Presentation

My position involves synthesis and development of multilayer-based optics for neutron polarization at neutron sources such as e.g. the European Spallation Source (ESS).

Synthesis is performed by ion-assisted magnetron sputter deposition with a particular emphasis at the formation of the multilayer interfaces.

Process development, plasma analysis, analysis of magnetic properties, and structural and chemical characterization of the multilayers by techniques such as X-ray reflectivity, transmission electron microscopy, and photoelectron spectroscopy are important components of the project.

In addition, neutron reflectivity measurements at the Institute Laue Langevin (ILL) in Grenoble, France, or other neutron facilities, will be performed. Modelling and simulation of X-ray and neutron reflectivity is included in the work tasks to reach an increased understanding of the multilayer morphology.

I am very open for any type of collaborations and always open to learn!
