Instrument Status Review GSC Meeting October 2009 1
Quick Status NICI Campaign and Open Science going well Efficiency enhancements considered for 2 nd quarter 2010 Flamingos 2 Now undergoing on-site Acceptance Testing and Commissioning at Gemini South Acceptance Testing scheduled complete late (October) 2009 GNIRS Substantial progress; significant setbacks Mid 2010 commissioning now scheduled GMOS-N CCDs GPI HIA selected as Integration and Test vendor Ready for integration into GMOS-N mid-2010 Assembly of major components now underway Delivery to telescope no sooner than early 2011 GeMS (MCAO) Work continuing with incomplete staff Laser expected this year Commissioning with GSAOI 2011A 2

NICI Science Campaign fully underway Available for general use as of 2009B Several upgrades in planning: Dichroics to replace 50/50 mirror but manufacture is difficult Additional filters ordered Optimized Spider, Pupil, and Focal Plane Masks mostly delivered Installation depends on delivery and end of 2010A observing block(s) Spare DM in procurement; possible delivery by end of year 4
Flamingos 2 First light images 5
Flamingos 2 Currently undergoing final acceptance testing and commissioning at Cerro Pachón On-telescope Acceptance Testing underway New Gate Valve baffle fixed K- band background; wheel mechanisms improved Array Dead pixels continue to be confined in one area New defects seen in first postship warm test of the array New HAWAII-2 ordered expected delivery by December Still no R3000 grating. Cold clamp to decrease pre-cool times is being tested New baffle mechanism currently limits F2 to side-looking ports F2T2 awaiting F2 and GeMS 6
GNIRS 7
GNIRS... lots of progress We now have a very good Aladdin-3 science array and a 3- quadrant spare + eng. Grade; mechanism and MUX tests underway OIWFS testing with Engineeringgrade array now complete Many optics and assemblies aligned All motors and sensors have been tested warm and are functional Vacuum tested; cold tests pending GNIRS Offner Assembly Testing at NOAO 8
GNIRS... and a few steps backwards Offner secondary scratched Replacement received and accepted, testing pending Continued lens coating problems (3 lenses) Limited to stoned and recently coated lenses from one manufacturer Internal Gemini Escalation Team worked with vendor to identify some problem areas in coating process Discovered a change in coating recipe from vendor Re-commission with1 good, 1 uncoated and 1 hot lens; replace hot and uncoated later when proper coatings can be procured OIWFS work took longer than expected now tested and working New bottom line: Acceptance Testing Feb 10; to Telescope Apr 10 9
GNIRS Optics coatings An unfortunate recurring problem with GNIRS optics note coating failure (crinkled areas) 10
GMOS-N CCDs Hamamatsu CCD in Socket with Cable 11
GMOS-N CCDs Hamamatsu won CCD down-select One Engineering-grade detector already delivered 3 Science-grade detectors selected, but awaiting verification of specifications Issued Contract to HIA for Integration and Testing Will use new ARC (SDSU) Generation 3 controller 4-channel readout should lead to faster reads Decided against prepping MIT/LL focal plane as a backup Contract work I&T timescale longer than anticipated delivery to Gemini North in 2 nd quarter 2010 Integration into GMOS-N will occur post-delivery 12
GMOS-N CCDs 13
GPI GPI dewar with new paint job 14
GPI Lots of recent GPI Progress Cal box nearing completion Integral Field Spectrograph dewar cold cycled New low-vibration cryo-coolers tested Integration and Testing plans re-worked Apodizer choices made MEMS still not delivered a contingency run is now scheduled Integration and Testing scheduled to start February, 2010 Acceptance Testing completion scheduled for end of 2010 Potential for delays in Integration and Testing, but working hard to minimize the possibility 15
GeMS Gemini MCAO System The laser infrastructure is now mounted on the Gemini South telescope. 16
GeMS Gemini MCAO System Laser Service Enclosure installed on telescope undergoing fine tuning and adjustments now Beam Transfer Optics some alignment completed; other tasks behind schedule Laser Keck laser undergoing Factory Acceptance Testing: finding bugs with software, but general specs looking good Laser Gemini laser delivery still scheduled for late 2009 Canopus (the AO bench) software upgrades and new features implemented; cooling system re-design on going Resource-limited: currently team operates on average at 60% of scheduled completion level due to operational needs (F2...) 17
GeMS Gemini MCAO System 2009B Plans Infrastructure Integration and Testing Beam Transfer Optics installed and commissioned Canopus cooling resolved Canopus wavefront sensor work If laser is received, commission inside the support enclosure 2010A + Plans Implementation of Laser Bench Beam Stabilizer system on telescope First light of Laser Guide Star Lab test Canopus with GSAOI and integrate at the telescope First light with Canopus towards end of semester 2011A Science commissioning 18
Summary NICI Full operation Upgrades ~2 nd quarter 2010? Flamingos 2 Commissioning late 2009B Not in time for 2010A call GNIRS Continued schedule delays due to coating failures Likely ready for commissioning in 2010A GMOS-N CCDs GPI CCD and I&T contracts issued Integration into GMOS ready late 2010A 2010 is Integration and Testing year Delivery to telescope no sooner than early 2011 GeMS (MCAO) Schedule hindered by late laser and limited human resources Commissioning with GSAOI 2011A 19
