  1. Magellan F/5 System Status A.Szentgyorgyi/SAO/30 Apr 2005

  2. Overview

  3. Core Elements Wide field corrector & ADC very similar to MMT. Instrument adapter to provide interface from MMT mounting to Clay rotator. Topbox for Megacam shutter & filter handling. Wavefront sensors included in instrument or topbox functionality. F/5 Secondary supplied by Magellan. Software interface to Clay guiding and mirror support software. Ancillary handling fixtures including substantial lift/tranport cart.

  4. Wide Field Corrector Optical Elements

  5. Wide Field Corrector Optical Elements

  6. Optical Fabrication • Fabrication by Goodrich/Danbury complete • Acceptance on 15 Dec 2004 • Shipped to Cleveland Crystal for AR coating • Coating in process • - Lens 4 coated to spec. • - Prisms coated • - “Hard” lenses still ahead • - Getting started is usually biggest gating item • - Expect completion by 1 June 05

  7. Selected Sol Gel for WFC Optics AR Coating

  8. Fabrication of Lens Cells • ADC bearing complete • Interface ring (steel) complete • Lens cell (Invar) work awaiting interface • ring fit check • Expect completion in time to start bonding in June • Performed fit check of interface ring • 21 Apr 2005

  9. Fit Check of Interface Ring • Fit is very tight • Tolerance on radial misalignment few 0.001” • Bore of telescope is ovalized with TIR ~0.008” • TIR of Interface ring referenced to rotator bearing is 0.002”-0.003” (radial) • -> Well within error budget

  10. F/5 Lift Fixture • MMIRS requires a very large lift • capabilty • WFC requires long extension • and precise placement • Fabrication in process • Design detailing nearly complete • Delivery by Aug 05

  11. Schedule for Completion of WFC • Feel full fit check and exercise of fixturing required before bonding Len 1 & 2 into • cells. • SAO is moving laboratories to new building at end of year. • Duration of move/down time TBD. June 05 All lenses back from Cleveland Crystal June/July 05 Bond Lens 3 & 4 & ADC prisms into cells Aug 05 Ship lift fixture and WFC fixture to LCO Oct 05 Final fit check, exercise lift fixture Nov/Dec 05 Bond Lens 1 & 2 into cells Jan 06 Ship to LCO

  12. Topbox Status (Cont.) • Topbox nearing completion • All axes have been controlled • in test set-up through prototype • PMAC controller from • LINUX platform • Testing to continue through • Summer 05 • Delivery date to LCO TBD

  13. Top Box Status • Sloan filter contract will be let to SAGEM • next week • Filters will be single substrate, all- • interference monoliths

  14. Wavefront Sensor • All components in house and tested under Linux control • Prototype testing in progress • Integration to Topbox and full system test in Jun/Jul

  15. Software Held interface meeting @ SAO w/ Skip Schaller and Alan Uomoto 14 Apr 05 Expect to have working software at time of delivery in early 2006, however will refine interfaces between delivery of WFC hardware and delivery of secondary Will bring Minicam as pathfinder for data acq. interfaces in mid-2006.

  16. Project Status All WFC optics fabricated to spec. WFC coating in progress @ Cleveland Crystal ADC bearings complete Rest of lens cell structures complete by June 05 Lift fixture @ LCO Sept 05 Instrument Adapter delivered 23 Apr 05 Topbox not on critical path -> near completion

  17. Project Status Expect on-schedule delivery of full WFC harware in early Jan/Feb 2006. First light (MiniCam) depend on delivery of F/5 Secondary
