Abstract
The coherent soft-x-ray scattering experiment CXS has been developed to study nano-structured magnetic and nonmagnetic thin film samples in transmission or reflection geometry. A nanometer precision movable sample stage in a 1 Tesla magnet vector field together with a movable CCD detector, variable in sample – CCD distance, allows both XMCD and XMLD experiments in transmission and reflection as well as imaging techniques such as Fourier transform holography and ptychography.
Highlights
The second part is a yoke-like rotator with four slots for sensors, e.g. a photo diode, rotatable by 340° relative to the sample holder
CXS: Coherent X-ray scattering at the UE49-SGM at BESSY II
The setup is very flexible in its scattering geometry via an in vacuum movable CCD detector, as shown in Figure 2, which allows experiments to be performed in both transmission and reflection
Summary
The setup is very flexible in its scattering geometry via an in vacuum movable CCD detector, as shown in Figure 2, which allows experiments to be performed in both transmission and reflection. The CXS end station (see Figure 1) at UE49-SGM (Helmholtz-Zentrum Berlin für Materialien und Energie, 2016) allows utilizing the high coherent photon flux from a BESSY II low-beta undulator for x-ray interference based experiments. The CXS is optimized for membrane window samples
