UNIVERSITY of CALIFORNIA OBSERVATORIES LICK · KECK · TMT

UCO is a Multi-Campus Research Organization of the University of California with administrative

center and optical labs in Santa Cruz and an infrared lab at UCLA.

UCO is primarily in place to efficiently develop and manage the O/IR facilities for UC astronomers.


Campus Facilities• UC Santa Cruz (UCSC)

– Optics Laboratory– Laboratory for Adaptive Optics– Engineering Group (mechanical and electronics)– CCD Detector Laboratory– Scientific Programming Group– Administrative Services/Business office

• UC Los Angeles (UCLA)– Infrared Laboratory - led by UCO Associate Director Ian McLean– Design, development and fabrication of IR instruments– Responsible for Gemini (Lick); NIRSPEC, OSIRIS and MOSFIRE (Keck)– Provided KCAM, SHARC and part of NIRC2 for Keck AO– IRIS for TMT – Professor James Larkin (UCLA IR Lab)

• UCO is a “full service” instrument facility


• Lick Observatory– 3m telescope

• LGS AO

– 1m telescope

– KAIT robotic telescope• SN discovery

– APF robotic telescope• Vogt Planetometer


Lick Observatory Instrumentation• Telescope Control System• Guiders• Hamilton echelle spectrometer (Vogt)• Kast double spectrometer (Miller) • PFCam, PF corrector, PF ADC (Bolte, Epps)• Gemini Twin-channel IR imager/spectrometer (McLean)• First astronomical AO system (Max/Gavel)• First astronomical laser guide star (Max/Gavel)• VILLAGES (MEMS-based optical AO system)


• UCO instruments at Keck Observatory:– HIRES

– ESI

– DEIMOS

– NIRSPEC (UCLA)

– OSIRIS (UCLA)

– K1 ADC

– MOSFIRE (UCLA/CIT/UCSC)

– HIRES detector upgrade

– LRIS-R detector upgrade

– Keck secondary mirrors


• Grating cross-dispersed R=40000 spectrometer operating from 310nm-1000nm

• 5 years/$4M completed in 1992, one of first three Keck instruments

• PI: Vogt• Redefined IGM studies,

dominated stellar abundance studies, discovered about 1/2 the known extra-solar planets

HIRES


• ESI: prism cross-dispersed optical echellette spectrometer and imager

• Best optical imager at Keck (0.3 FWHM)

• Space frame structure• Small elastic flexure

compensated with lookup table to 0.2 pixels RMS

• >30% total throughput at most order peaks

• PI: Miller, optical design: Epps, engineering: Radovan/Bigelow


• Wide-field, two-arm optical MOS and imager

• Eight-CCD mosaic focal plane

• Active flexure compensation

• 19,000 lbs• Optics fabrication at UCO• $10.5M; PI Faber• Most in-demand

instrument at Keck Obs

DEIMOS


Astronomical coatings facilityMgF2 + sapphire with ion-assisted deposition, spin-coat 41-in prisms, harden and add

hydrophobic treatment


• NIRSPEC: the first cryogenic cross-dispersed IR echelle spectrometer; also has low-resolution mode and slit-viewing camera; 1-5 microns.

• OSIRIS: A lenslet-based Integral Field Spectrometer for 1-2.5 microns for use with the Keck 2 Laser Guide Star AO system

1999

2005


• MOSFIRE: a powerful multi-object spectrograph and imager for 1-2.5 m

• UCLA/UCO/Caltech collaboration that is working very well– PI: McLean (UCLA)– PS: Steidel (CIT)– Optics: Epps (UCO)– IR Detectors (UCLA)– Rotator (UCO)– Cryostat (CIT)– $12.5M

• Industry participation


• UCO is committed to using the experience, infrastructure and expertise developed in building instruments for Lick and Keck Observatory, and applying that to the design and fabrication of instruments for TMT

• We are already into Conceptual Design for two instruments to be reported on later:– WFOS/MOBIE (Santa Cruz led)– IRIS (UCLA led)

CONCLUSIONS


We recognize that these are very significant undertakings and anticipate and welcome partnerships

to design and build major subsystems.
