Previously we have reported on our work on coating a truncated-cone-shaped engineering (not high quality in terms of smoothness) mandrel and have removed the layers, intact, on the inside of an electroform with a cylindrical, truncated-cone geometry. We have advanced to using a high quality (about 0.5 nm) smooth truncated cone. We report our latest advances in refining our fabrication techniques and the results of X-ray measurements. The X-ray measurements made at the Argonne APS SRI-CAT 2-BM-B beam-line were at 10 and 30 keV. The results showed that we had produced excellent Si/W multilayers on the inside of a 10 cm long by about 10 cm diameter truncated cone shaped mirror. We estimate the reflectivity of the layers at the primary Bragg peak to be well above 10%. We also show that the multilayers were uniform around the mirror.
