Scope

Soft X-ray microscopies are powerful analytical tools for addressing problems in nanosciences. They achieve high spatial resolution with state-of-the-art Fresnel zone plate optics demonstrating now better than 10nm spatial resolution. The wide tunability of the wavelength at synchrotron sources provides inherent elemental specificity and the pulsed time structure at current X-ray sources allows for stroboscopic pump-probe experiments to study sub-ns dynamical processes. Utilizing strong magnetic dichroism effects with polarized soft X-rays at specific photon energies enables a quantitative imaging of nanoscale spin dynamics. The high penetrability of soft X-ray has opened nanotomographic capabilities which are being used in biological and environmental areas.
This workshop reviews recent achievements with full field soft X-ray microscopies in nanomaterials sciences such as magnetic materials and environmental sciences and envisions future capabilities.
