Two-Dimensional Differential Deposition and Erosion for Thin-Shell Figure Correction, and Non-Distorting, High-Energy X-ray Multilayers

data.nasa.gov | Last Updated 7 Sep 2018

We propose to continue our development of two-dimensional differential deposition and erosion, a novel methods for high-throughput surface height error correction in thin-shell cylindrical mirror substrates. We also propose to develop non-distorting X-ray reflective multilayer coatings for use above 80 keV. Our specific research objectives are: (a) develop two-dimensional control of film deposition and erosion to correct both low- and mid-frequency surface height errors in cylindrical, thin-shell mirror substrates, and (b) develop high-efficiency, non-distorting, zero net-stress, and stress balanced, reflective multilayer coatings for use above 80 keV.
