Pack‐rolling has been utilized to roll foils of Mg, Al, Sc, Ti, V, Mn, Fe, Y, Zr, Mo, Ag, In, Nd, Gd, and Dy for use asK‐ andLIII‐edge filters in x‐ray experiments in the 1–15 keV range. Sc, V, Y, Zr, Ag were readily rolled to 0.5–1.0 &mgr; thickness; Mg, Ti, Mn, Gd, and Dy to 1.8–4.5 &mgr;; and Mo and In to about 6.0 &mgr;. Details of the rolling procedures for producing 10–20 cm2foils for monochromatizing x‐ray beams are given. The thickness uniformity of the pack‐rolled foils was found to vary from ±10% at >4 &mgr; to ±30% at <1 &mgr;, as measured by241Am alpha transmission. The successful fabrication of thin, pigmented, plastic films for Ge, SrF2, and Sc2O3K‐edge filters is briefly described.
