Paper Abstract

An X-ray telescope for the LAMAR instrument has been designed, built and tested at the Smithsonian Astrophysical Observatory. In addition, telescope performance has been verified at the NASA Marshall Space Flight Centers long X-ray beam facility. After X-ray testing and data reduction is complete, the telescope will undergo vibration testing. Post-vibration visible light tests will then verify no change in performance. The design and fabrication of this high-throughout Kirkpatrick-Baez geometry telescope incorporates the use of advanced composite materials (aluminum-graphite/epoxy) to provide a thermally stable structure. A computerized figure formation system is used to attain the approximate parabolic curve of each optic. Each optic is supported by ten titanium flexures to provide the necessary decoupling between the stiff structural support module and the glass mirrors. The design, analysis and fabrication` ofthis module will be described, as well as the numerous problems encounted and the solutions developed, in this protoflight project.
