FLITECAM April 28, 2009 Ian McLean (Principal Investigator) UCLA Infrared Laboratory University of California, Los Angeles
OVERVIEW & SCOPE OF WORK SUMMARY • Current Status: • Six additional filters (narrow band) designed, ordered and received • Meeting concerning original airworthiness/pressure testing of our cryogen reservoirs – canceled by DFRC as being unnecessary. • FLITECAM is complete & stable. It is currently in storage. • Remaining Tasks (for FY2009): • Inspect filters, prepare drawings/shims, develop installation plan • Installation will likely occur in late July when resources are available • Understand changes to MCCS and update as required – no progress yet • Hiring freeze at UCLA • Understand Instrument Conformity • USRA pulling Instrument Conformity package together to submit to NASA (May).
QA Issues and Mitigations • Interface to MCS (minor) We completed the software interfaces as outlined below under the previous USRA plan but will need to make changes as required to accommodate the new MCS • Tier 1: Basic Connectivitycompleted • Tier 2: Mission Data Handling completed • Tier 3: Command Handling completed • Tier 4: Observing Scenarios – FLITECAM code complete, tested against MCS until stopped • We may need to establish new interfaces and tests. • We contacted our previous software engineer but cannot secure her services full-time • She reviewed current SOFIA documents and reported no significant impact • There is a hiring freeze at UCLA right now so we cannot search for a new software engineer; there is also not enough work for a 100% FTE • We must defer this work until later in FY09 or possible FY10
The New Filters • Paschen alpha: Center Wavelength = 1.875 m • Bandpass (FWHM) = 0.0188 m (1%, or R=99.7) • Start = 1.8656 m End = 1.8844 m • 2. Paschen alpha cont.: Center Wavelength = 1.900 m • Bandpass (FWHM) = 0.019 m (1%, R=100) • Start = 1.8905 m End = 1.9095 m • 3. Ice: Center Wavelength = 3.050 m • Bandpass (FWHM) = 0.152 (5%, R = 20) • Start = 2.974 m End = 3.126 m • 4. PAH: Center Wavelength = 3.290 m • Bandpass (FWHM) = 0.090 m (2.74%, R = 36.6) • Start = 3.245 m End = 3.335 m • 5. Narrow band L (nbL): Center Wavelength = 3.60 m • Bandpass (FWHM) = 0.18 m (5%, R = 20) • Start = 3.510 m End = 3.690 m • 6. Narrow band M (nbM): Center Wavelength = 4.80 m • Bandpass (FWHM) = 0.144 m (3%, R = 33.3) • Start = 4.728 m End = 4.872 m

FLITECAM Documentation Status Master Data Listcomplete – documents on web site & FLITECAM Cabinet FAA Component Maintenance Manual complete All drawings up to date – FLITECAM document storage cabinet & web site Draft Integration & Commissioning Plan complete Software Documentation is complete and up to date UPDATE: RECENTLY supplied Master Drawing List details to USRA as requested.
FLITECAM MILESTONES Next major event is installation of new filters – July 2009. Then, integration with new MCCS build – needs software support.
CONCLUSIONS • Work for 2009: • Install new filters • Plan in place to carry out work in late July • Software interface to new MCS – hire software engineer (?) • Delay implementation; use part-time resources for now • Submit materials for conformity review/approval • Probably now early FY10 • Constraints: UCLA personnel are not available for conformity activities until summer 2009 at earliest. • UCLA staff are building MOSFIRE for Keck and GPI for Gemini-South. Both projects are moving along well. • Budget: OK (= $150k for FY09; $47,500 remains to be funded) • Includes filter purchase and installation, plus a part-time programmer (50%)
