Timeline

• PPAE: June 2013 in Heidelberg

• Juli 2013 shipment

• Sep/Oct 2013 reintegration and lab-tests

• Nov 2013 – Jan 2014: seeing-limited com

• Mar 2014: Test-run Binocular observing cancelled

• Jun/Jul 2014: Upgrade LUCI2 for AO

• 2014B: LUCI2 AO-commissioning

• 2014B: LUCI2 seeing-limited potentially available for users

• 2015A: LUCI2 AO potentially available for users

Comparison LUCI1 vs. LUCI2

• Hardware practically identical

• Detector in LUCI2 H2RG, higher and homogenous QE

• New Software (new detector, binocular observing)

scripting via XML-files

• New Observer User Interface

• New RTD

• New (and much faster) LS/MOS-acq. tool

The highlight – luck with the weather • 3 Runs in 2013B: Nov 9-14, Dec 12-18, Jan 15-21

• 4.25/6, 5/7, 6.25/7 nights 15.5/20 nights!!!

(120/150 nights LUCI1-com dome closed)

• Almost no telescope downtime

• No power outages, no other catastrophies

basically done with the night-time com-activities!!!

Detector-characteristics

But: LUCI1/2 dichroic cuts off at 0.89/0.95µm

LUCI1 better for z-band, LUCI2 better for H-band and redder

New Software

Can be started from everywhere

Data go into server + can be downloaded from there

No direct access to the LUCI machine for user!

Some highlights

W3, K-band, 30min, 0.55“ FWHM

(prepared by D. Thompson)

Comet Lovejoy, K-band, 60sec

MOS-spectra of very faint z > 2 galaxies in MPE-fields

210K, 160min, all galaxies show Hα and [N II] 6583 Å

(prepared by J. Kurk)

Summary

• LUCI2 in seeing-limited mode basically ready

• Detector/readout SW stable

• Instrument SW stable

• MOS-acq. tool extremely fast (down to 12min) and reliable

• Data processing ongoing

• Some cosmetic instrument SW optimization ongoing

• Manuals pending

Decision board/LBTO if and when LUCI2 may be offered
