Summary: The paper presents a more general analytical theory of X-ray beam propagation through compound refractive lenses (CRLs) compared to prior studies. It examines the problem of nanofocusing with CRLs and discusses the limitations on focusing efficiency caused by radiation absorption in the lens material. The X-ray transverse beam size at the focus is found to be smaller by a factor of gamma = beta/delta compared to just behind the CRL.

Summary: In this study, we measured and modeled tilted X-ray refractive lenses and validated the results using at-wavelength metrology obtained from X-ray speckle vector tracking experiments. We explored the potential applications of tilted X-ray lenses in optical design and found that tilting 1D lenses around their focusing direction allows for smooth fine-tuning of their focal length. Experimental demonstrations showed a continuous change in the apparent lens radius of curvature, allowing for a reduction up to a factor of two. Possible applications in beamline optical design were proposed.

Summary: Cost efficiency and defect passivation are the two major challenges for thin-film solar cells. Increasing the Ga/In ratio improves performance but conflicts with economic interests. This study investigates Cu(In,Ga)Se-2 cells and finds that In-rich cells have better performance and more uniform distribution compared to Ga-rich cells. The effect of Rb suggests more effective passivation of structural defects.

Summary: Aberration-free x-ray optics are essential for nondestructive scanning x-ray microscopy with high spatial resolution. However, even state-of-the-art x-ray optics often have residual lens aberrations, which can be corrected by integrating additional optical elements into the focusing device. In this study, corrective optical elements were integrated into planar nanofocusing x-ray lenses by structuring a phase plate into the lens chip via focused ion-beam milling. The results showed diffraction-limited performance and a significant reduction in residual intensity outside the focus.

The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
