Paper Abstract

We are studying on a press forming of a 0.3-mm-thick foil in order to make advanced thin-foil substrates with a two-stage reflector for large X-ray telescopes. We press-formed one sheet of aluminum foil using a stamping die with high accuracy, and then obtained a two-stage reflector with a length of 100 mm/stage. The accuracy of its shape along the axial direction reached to 10 μm. Since long substrate has an advantage for fabrication of large X-ray telescopes, we are making a two-stage reflector with a stage 200 mm long. The stamping die for the long substrate was processed by the ELID method. We will perform a press-forming in this summer. In order to evaluate the press-formed substrate, we have made a surface measurement system. It is possible to response to a fabrication of the substrate quickly.
