6. MMIRS 6 Harvard-Smithsonian Center for Astrophysics Magellan SAC 9/05 Current Status Optics: Contract has been awarded to Janos. Mechanical Design: Solid modeling 98% done. Vacuum vessel RFQ released. LN2 tank/optical bench RFQ finished next week. Electrical Design: Design and component selection are complete. Detailed drawings in progress. SWIRC pathfinder controller in operation reading 32 channel MMIRS engineering device at MMT. Software: Design complete. Many heritage components. Test dewar: In house. Servo controlled cooling tests about to begin. Detector testing to follow.

7. MMIRS 7 Harvard-Smithsonian Center for Astrophysics Magellan SAC 9/05 LCO Issues MMIRS instrument weight 3244 lb. – can be lifted by crane in dome. MMIRS weight at Cass (w/ adapter, &c) is 4471 lb. – also acceptable. SAO & LCO collaborating on ops plans for prepping, mounting, operating and (if necessary) repair MMIRS @ LCO – clean room essential component. Expect to refine ops plan during October 2005 engineering.
