Abstract

A comprehensive program has been developed for the production of focal plane assemblies (FPA) for use on the University of Arizona Near Infrared Camera and Multi-Object Spectrometer (NICMOS) instrument which is to be installed in the Hubble Space Telescope (HST). This paper describes the current schedule, tests to be performed, test conditions and unique test facilities of the flight FPA qualification test program. This test series is intended to validate design, assembly, performance and reliability of flight qualified FPAs. Also described are the design features, performance characteristics and test results obtained with prototype FPAs used as engineering evaluation units prior to committing the flight qualification units to manufacture. The qualification tests will demonstrate performance margins over and above requirements under operating environmental conditions. Included in the qualification tests are electrical, mechanical and thermal tests. Random vibration tests and mechanical shock tests will be performed at 1.5 times the load level specified for acceptance requirements. The random vibration tests simulate launch conditions and will induce stresses to uncover any potential structural deficiencies that might exist. The mechanical shock tests will simulate potential impacts incurred as a result of handling or transport. The qualification test program is intended to maximize confidence in the quality and integrity of the flight FPAs.
