Paper Abstract

Two identical Wolter type 1 mandrels, with 50 cm diameter and 8.4 meter focal length, to be used by NASA/MSFC for their Constellation-X mirror development program, have been produced and tested by Carl Zeiss. In August 1999, both mandrels have been delivered to MSFC. Key optical performance of both mandrels: On-axis HEW; < 3.2 arc sec and micro-roughness: better than 0.30 nm RMS. We will report about mandrels design, fabrication, test and verification of their X-ray optical performance.
