Overview
![Page 3: Magellan F/5 System Status](https://reader035.fdocuments.us/reader035/viewer/2022062808/5681540a550346895dc208cb/html5/thumbnails/3.jpg)
• 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.

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

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
![Page 9: Magellan F/5 System Status](https://reader035.fdocuments.us/reader035/viewer/2022062808/5681540a550346895dc208cb/html5/thumbnails/9.jpg)

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

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
![Page 12: Magellan F/5 System Status](https://reader035.fdocuments.us/reader035/viewer/2022062808/5681540a550346895dc208cb/html5/thumbnails/12.jpg)
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 CrystalJune/July 05 Bond Lens 3 & 4 & ADC prisms into cellsAug 05 Ship lift fixture and WFC fixture to LCOOct 05 Final fit check, exercise lift fixtureNov/Dec 05 Bond Lens 1 & 2 into cellsJan 06 Ship to LCO
