Scientific paper

Results obtained with the use of galvanoplastic technology for the production of ultrathin (below 1 mm wall thickness) components for use in future imaging X-ray experiments are described. Ultrathin mirrors of different geometries (flat, conical, and Wolter 1) were produced in this manner. Initial data obtained from optical tests of the shells produced indicate the anticipated difficulties in appropriately mounting and supporting ultrathin shells to avoid the degradation of their shape and, consequently, their optical properties. However, the estimation of angular resolution obtained from optical tests using two different mounting systems confirms the high shape quality of replicated shells. The preliminary results indicate X-ray reflectivity of 80 percent at incidence angles below 0.4 degrees at Fek-alpha.
