LBTI Summary

Outstanding LBTI on-sky results during 1st three nights on the sky

• Obtained instrument First Light!• Obtained instrument first Fringes!• Telescope is well behaved, i.e. stable enough

to easily interfere the beams.

Next LBTI Observing Block November 4-6• Concentrate on Adaptive Optics Imaging at 2-10µm• Attempt initial interferometry science.

FY11 Project Schedule• Resources now available to support 10+ commissioning nights

during FY11.• NIC Imager scheduled to start commissioning in March 2011• A fraction of the nights will focus on science observations of key

science targets.3

FIRST Light and Fringes!Beta Peg: Combined 10µm image from the LBTI imager. Image is “seeing limited” under poor weather conditions (seeing ~1.2 arc sec). It does demonstrate the LBTI instrument and LBTO telescope’s 23 meter resolution capabilities and stability “right out of the box”.

The Next Observing RunNovember 4-6, 2010

LBTI November observing will be used to attempt two separate goals: 1.AO imaging, and 2.Interferometry Science.

We will intersperse tasks from each area during the run, to maximize use of on-sky time.

True Binocular Ops Definition:Activities in preparing the telescope for coordinated binocular (simultaneous) observations. Activities include Instrument ports commissioning, software, mirror mount upgrades, mirror covers, two secondary/tertiary mirrors operational.

Daytime AO Commissioning Definition:Secondary mounted with artificial source at center of curvature (See image on next slide) and wave front sensor. Testing conducted during the daytime hours with dome closed. Repeat of test suite performed in Italy that will verify proper, and expected on-telescope performance.

On-sky Commissioning Definition:Open dome, closed loop testing using natural guide star. Italians have asked for 50+ nights with seeing “good seeing”. This is the driver for the 4-5 month on-sky commissioning period. LBTI expect near normal AO operations to be achieved by late-Fall ‘10

Telescope re-installation:Includes mechanical installation of the Beam Combiner, Wave Front Sensors, electronics.Internal alignment and integration included the instrument alignment with the optical axis of the telescope. Alignment will be accomplished with an infrared test camera, and prototype nulling interferometer (BLINC/MIRAC)

LBTI AO Commissioning:Commissioning tasks associated with the operations of the first dedicated wave front sensor (Unit #1). Unit # 2 commissioning will take place after the AO Secondary Mirror unit #2 is commissioned in calendar 2011.

AO Interferometry Commissioning:Commences after AO Secondary Mirror #2 is installed and commissioned and when funding profile supports the activity.

Other Project Activities

The Project has also pushed a head with the testing of the NIC imager:

• Limited progress due to limited resources… i.e. everyone was concentrating on support the installation and first observing run.

• Testing in continuing in the lab with performance characterization.

• LMIRCam testing finishing up in Virginia. Expect delivery in late November.

Item #1: LBT Schedule dependency -Telescope construction schedule is on the critical path.

Current StatusCompletion of the interferometric capable telescope now scheduled for late Fall 2011. Expected Resolution/ImpactLBTI expects to move forward with commissioning tasks to the limit of the telescope capabilities. AO Unit #2 remains on the critical path to Science Operations. Expect Unit #2 to be delivered in May 2011.

Description

Item #2: LBT Performance -Telescope performance has impacts on instrument productivity.

Current StatusTelescope commissioning continues. Presently no known issues of telescope performance are show stoppers. LBTO is actively addressing all issues. First light performance showed no issues that cannot be addressed and overcome before the observatory commissions interferometric capabilities. AO performance meets LBTI requirements. Expected Resolution/ImpactLBTI project continues to monitor the evolution of the telescope system.

Item #3: Instrument Integration Schedule -Instrument commissioning schedule is ambitious for 20 nights.

Current StatusLBTI struggles with sufficient funds for full commissioning schedule and with the log jam of telescope facility commissioning tasks that take priority.

We have been able to jump the line and start limited commissioning. Project plan and finances support 10 nights of on-sky commissioning in FY11. Expected Resolution/Impact
