Paper Abstract

We are developing grazing-incidence x-ray optics for a balloon-borne hard-x-ray telescope (HERO). The instrument will have 200 cm2 effective collecting area at 40 keV and an angular resolution goal of 15 arcsec. The HERO mirror shells are fabricated using electroformed-nickel replication off super-polished cylindrical mandrels. The angular resolution goal puts stringent requirements on the quality of the x-ray mirrors and, hence, on mandrel quality. We used metrology in an iterative approach to monitor and refine the x-ray mirror fabrication process. Comparison of axial slope measurements of the mandrel and the shells will be presented together with results from x-ray tests.
