Background Equatorial Astronomical Measurements Focal Plane Assembly (Refurbished HI STAR SOUTH)

Abstract : The objective of the contract was to revise the existing design and to disassemble, modify, reassemble, test, and deliver one customer-furnished HI STAR SOUTH Focal Plane Assembly (FPA) for use on the Background Equatorial Astronomical Measurements (BEAM) program. A second FPA was furnished by the customer for parts. The first part of this report discusses the changes made in the design and provides photographs and drawings showing the various stages of modification and assembly of the focal plane. The major portion of the report presents the final performance and environmental test data taken on the modified FPA. A brief description of the test setups used for each test is provided, with a summary of the method of measurement and the resultant data. The data taken on the spectral filters (transmission vs wavelength) are included in Appendix A. Appendix B gives the temperature sensor calibration curves.
