Research at XM-1

The current research activities utilize specific features of full-field soft X-ray transmission microscopy


- elemental specificity of x-ray absorption

- high lateral resolution (currently down to 15nm) provided by Fresnel zone plates as optical elements

- large field of view of 15-20μm for a single image, which can be tiled up to even larger images

- recording images in varying external environments (magnetic fields, temperatures)

- sub-ns temporal resolution utilizing the pulsed time structure of the storage ring in a stroboscopic pump-probe scheme

- magnetic phase contrats imaging


Therefore XM-1 is used to image at high spatial and temporal resolution microscopic structures with applications to magnetism, materials and environmental science and biology.

Typical scientific topics include

 

Magnetism
- spin current induced domain wall motion
- spin torque induced dynamics
- stochastical character of nucleation processes
- microscopic magnetization reversal behaviour in pattermed media
- fast magnetization dynamics in patterned elements


 


Materials science
- electromigration processes and void formation in interconnects


 

 

Environmental Science
- formation of cement


 


Biology

- imaging of Malaria infected blood cells
- 3D imaging of cell structures with x-ray tomography


 

Zone plate optics

- phase sensitive Fourier optics
- development of preparation techniques

- increasing the lateral resolution

- measuring zone plate efficiencies
