MOSFIRE Status Update
Bob Weber27 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
27 January 20102
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

27 January 20106
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
27 January 20107
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 down27 January 20108
Platform & Hexapod structures for alignment checks
27 January 20109
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 TMTBob Weber
27 January 2010
COO All-Hands Meeting
27 January 201011
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)
27 January 201012
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
27 January 201013
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)
