SOPHIE: A New Soft X-ray Ptychographic Microspectroscopy Endstation — •Tim A. Butcher, Nicholas W. Phillips, Lars Heller, Mirko Holler, Carlos A. F. Vaz, Armin Kleibert, Simone Finizio, and Jörg Raabe — Paul Scherrer Institut, 5232 Villigen PSI, Switzerland

The SOPHIE (SOft X-ray Ptychography Highly Integrated Endstation) endstation, newly developed at the Swiss Light Source (SLS), is designed for microspectroscopy in the soft X-ray range at synchrotrons. This energy range allows elemental and magnetic sensitivity for measurements involving 3d transition metals, which is key for studies in nanomagnetism. Soft X-ray ptychography is able to deliver a spatial resolution in the order of 5 nm, which can be extended to three dimensional imaging in a laminographic geometry. Currently, SOPHIE is located at the SoftiMAX beamline of MAX IV and will be returned to the SIM beamline after the upgrade to SLS 2.0. The first imaging results and the general capabilities of the endstation will be presented during this talk. This includes the successful imaging of non-collinear magnetic order such as the spin cycloid in bismuth ferrite.
