Abstract

Space test of x-ray multilayer mirrors on the surface of Russian orbital station 'Mir' revealed that after a 5-month space exposure, multilayers consisting of chemically interacting materials (Mo - Si and WSi₂ - Si) preserved their periods. Preannealing at 570 K for one hour was sufficient to stabilize reflectivity at 1.54 angstroms of mirror WSi₂ - Si with period 33.6 angstroms. Preannealing at 770 K for one hour was not enough to stabilize reflectivity at 1.54 angstroms of MoSi₂ - Si mirror with period 77.7 angstroms (after space exposure its reflectivity was increased by 18% as a result of interface smoothing influenced by space effect agents).
