8 keV x-ray zone plates.

摘要

Sputtered-sliced transmissive x-ray zone plates consisting of concentric rings of Al and Cu have been fabricated and tested using the 8.04 keV k-(alpha) line from Cu. Due to the need for high aspect ratios for this 1.54 (Angstrom) radiation, magnetron sputtering onto a rotating opaque central wire was chosen as the fabrication method. Both the fabrication technology and initial results are presented. 11 refs., 4 figs.
