Optical klystron FEL scheme for x-ray coherent harmonic generation at ISLF storage ring

The possibility of inserting an optical klystron on the storage ring of an Iranian Light Source Facility as a Synchrotron Radiation Free electron Laser for coherence harmonic generation in the soft x-ray spectrum has been studied. The study has been performed using the 3D FEL simulation code GENESIS 1.3 and in accordance with the available characteristic parameters of ISLF. Different potential ...

Laboratory cryo soft X-ray microscopy.

Lens-based water-window X-ray microscopy allows two- and three-dimensional (2D and 3D) imaging of intact unstained cells in their near-native state with unprecedented contrast and resolution. Cryofixation is essential to avoid radiation damage to the sample. Present cryo X-ray microscopes rely on synchrotron radiation sources, thereby limiting the accessibility for a wider community of biologis...

3D PSF Measurement for a Soft X-ray Microscope and Comparison to Theory

The transmission X-ray microscope’s 3D PSF exhibits an axial asymmetry that cannot be explained by an incoherent imaging model for either a lens or zone plate, with or without spherical aberration.

Partially coherent image formation with x-ray microscopes.

Image formation with partially coherent radiation is evaluated with the Hopkins formula and then applied to x-ray microscopy. Image characteristics expected from instruments with circular and annular pupils in partially coherent conditions are considered for two-point objects and a knife-edge object. The theoretically expected values for image characteristics that are easy accessible by an expe...
