Abstract

We had been developing replicated aluminum foil optics for previous missions such as ASCA, Suzaku, and, Hitomi. This sort of X-ray optics can be lighter but the angular resolution is limited to on the order of arcminutes. Thus, to improve the angular resolution with light performances, we have started developing electro formed X-ray optics. Electroforming is a technology that can transfer to a substrate with high accuracy by plating the nano-level structure of a super-precision master and makes it easier to fabricate Wolter type-I shaped two-stage full-shell mirrors.
