Management Of Optics

American Science and Engineering, Inc. designed the large X-ray optic for the HEAO-2 X-Ray Telescope. The fabrication of the optical surfaces, their assembly and alignment were subcontracted to Perkin-Elmer by AS&E. The HEAO-2 mirror was truly one of a kind, nothing like it has been built before. There was no prototype, no spare optical surfaces -- the one mirror assembly we built would fly. With the ambitious performance goals of HEAP so intensely dependent on the mirror, this subcontract was recognized from the beginning as key to the success of the program. Also, since X-ray optical performance could not be measured until 6 months after delivery, unusual in-process controls had to be placed on P-E throughout the subcontract to assure success. Management of this effort was extremely complex because of the intricate weaving of the responsibilities between the two companies and the close surveillance and participation by NASA and the Principal Investigator. This paper will describe the Yanagement Plan used to accomplish this program and the many revisions to that plan required as this unique state-of-the-art effort unfolded.
