12. Stratospheric Observatory for Infrared Astronomy Deutsches SOFIA Institut 18. Feb. 2010 SSSC Th. Wegmann SOFIA Fast Diagnostic Camera Replace FPI with a fast EM-CCD Camera for engineering flights to optically analyze the TA pointing stability (independent of HIPO or FORCAST), i.e. monitor star centroid location in focal plane with up to ~ 400 frames / sec ANDOR iXonEM DU-888 (BI) camera purchased and characterized (lab and on-sky, DSI telescope & Lick Observatory) Mounting plate for FPI flange built by KT First test at TA during line ops in September 2009 - Mechanical and optical interfaces: alignment OK, focussing OK - Photometric sensitivity was measured: FDC ~ 3 x more sensitive than FPI, limited by DAOF sky background (EM gain not usable) - High frame rates tested: optical analysis of SM-chopper with 249 & 295 frames/sec, fine drive system analysis with up to 400 frames/sec, extra-focal star images to characterize atmosphere (seeing) Currently flight configuration of FDC is prepared for a first flight in summer 2010 (TA Characterization Flight #2): - Control computer in ATR box to replace FPI controller on TA, optical link to user station, cable routing at TA - simultaneous data acquisition with FORCAST using FORCAST trigger puls - addition of GPS time stamps

13. Stratospheric Observatory for Infrared Astronomy Deutsches SOFIA Institut 18. Feb. 2010 SSSC Th. Wegmann Telescope Assembly Characterization and First Light (TACFL) The main aim is to determine the pointing stability of the TA, which is probably the most crucial single issue for airborne observatories. It is also intended to use this opportunity for producing a first light image. A working group, led by DSI Ames personnel and with the collaboration of USRA, was brought into being on 1/21 with the task of writing a test plan and a more detailed list of procedures for this flight. A version of the test plan that is complete but not final yet was circulated on 2/5. The flight is expected to happen in mid-April and to fulfill the following tasks: - Inertial stability evaluation from observations of point sources with and without FFI and FPI tracking - Tuning of the Quasi-static Flexible Body Compensation and try-out of WFI tracking - Various cavity environment tests - Getting first light images with FORCAST Several of the tests under the previous bullet will be carried out with FORCAST: - Test targets must be bright enough for both FORCAST in fast read-out mode and the images to see - Coordination with the FORCAST team needed w.r.t. Preceding mini line-ops, parallel activities during the flight etc. - The first light targets will be extended sources that make beautiful pictures Planning of the activities with the telescope during the first flight characterization flight
