The “On the Cover” information in Powder Diffraction, Volume 35, Issue S1 was incorrect.
It should read “On the Cover: The manuscript in this issue titled ‘CRL optics and silicon drift detector for P06 Microprobe experiments at 35 keV’ was written by Gerald Falkenberg, Frank Seiboth, Frieder Koch, Ken Vidar Falch, Andreas Schropp, Dennis Brückner and Jan Garrevoet. The figure (at left) shows characterization of the focused X-ray beam at 35 keV by ptychography and XRF edge scans on a siemens star test pattern.”
