Abstract
This paper documents the engineering design, fabrication, assembly, and test activities at SSG, Inc. that produced the CLAES Telescope Assembly. It includes a brief outline of the optical design as given by Lockheed Palo Alto Research Laboratory. Several major design and assembly areas are reviewed to highlight the driving design and performance constraints of the telescope. These include the dip-brazing process utilized on the structural sub-assemblies, and the fabrication process for the three flight mirrors. The telescope system alignment techniques and processes are reviewed, and include an outline of the verification test plan which covers the optical, structural, and cryogenic test procedures for the telescope. Test data is given and compared to the performance specifications. The last topic is a brief discussion of the lessons-learned from this telescope, and the follow-on diagnostic tests that are currently in process at SSG, Inc.
