MOSFIRE Status Update Bob Weber 27 January 2010 COO All-Hands Meeting
MOSFIRE Overview • Multi-Object Spectrometer for Infra-Red Exploration • CIT, UCLA, UCSC, Keck collaboration • NIR multi-object spectroscopy over 6.1’ x 6.1’ FOV; up to 46 objects simultaneously • Wavelength coverage: 0.9-2.5 µm (Y, J , H & K) • Commissioning: Keck 1 Cass by end of 2010
Recent Progress Summary • 3rd cool down completed successfully • Cold alignment confirmed • Installed mechanisms (FCS, Grating Turret, Pupil Mechanism, CSU) operated successfully in all gravity orientations • All science optics successfully mounted & aligned • All lenses aligned & bonded into cells (except field flattener) • Camera barrel assembled • Collimator barrel ready to be assembled • Science flats aligned & bonded

Lens Mounting Camera Lens #4 Installed Camera Barrel Assembled
Current Activities • 4th cool down preparations • Re-check cold alignment w/ science flats • More mechanism tests • Detector head cold tests • Focus mechanism tests (cold @ UCLA) • Install detector • Field flattener installation
Current Activities (Cont.) • Filter wheel cold tests • Wheel detent design modifications necessary • Cold tests in test chamber before 5th cool down • Guider assembly & alignment check • Assemble to front end cap • CMM metrology & adjustment • Alignment check w.r.t. instrument axis during 4th cool down
Looking Forward • 5th cool down (late March) • Install all optics • Install all remaining mechanisms • Install science detector • Optical tests • 6th cool down (May) • Flexure mapping • 7th cool down (late June) • Acceptance tests? • Pack & Ship (July-August?) • Commissioning (September?)
IRMSInfraRed MultiSlit Spectrometer for TMT Bob Weber 27 January 2010 COO All-Hands Meeting
Overview • IRMS is envisioned as “clone” of MOSFIRE • Fed by NFIRAOS • Three modifications required for TMT: • Alter mounting to attach to NFIRAOS • Alter field lens prescription for TMT • Alter guider system to OIWFS (on instrument wave front sensing)
Current Status • TMT preparing SOW for Conceptual Design Study • Design study period: (late 2010 thru early 2011) • UC Riverside is the design study lead • COO’s contribution (~$100K): • Design & cost required modifications to MOSFIRE • Develop schedule & cost to completion
COO’s Future in IRMS? • The IRMS team remains undefined • This is substantially a fabrication, procurement, and I&T project. To keep IRMS costs minimal, we have suggested that: • COO participates in project engineering/management • Mechanical re-design done by COO • I&T tasks should be done at CIT (infrastructure & experience exist)
