Commissioning campaign activity rationale
FLAO system external review, Florence, 30/31 March 2009 3
Phase I
Phase II
From FLAO_07 TOC
The two main phases of the commissioning campaign follow the idea to proceed in the test advancing in all system aspects (HW, control SW,data reduction SW) at the same time. So, the first phase milestones is a closed loop on-sky test with 200 modes and a bright star. This to recognize any serious problem in any of the components or procedures used.
The second phase will then optimize the system in all aspects and will contains the final test of the system on sky.

FLAO re-integration & alignment
1. System and sub-system functional test completed (compliance matrix). 2. LBT672, W#2 and IRTC installed at the telescope.3. FLAO aligned with retro-reflecting optics (including IRTC). (see
FLAO_06, FLAO_09)
Total duration: 22 days, daytime 22 days
FLAO system external review, Florence, 30/31 March 2009 6
FLAO system 1st light
1st corrected images on sky with 200 modes (engineering mode).
Task summary: verification of system performance at the telescope site in daytime. On sky test of source acquisition, pupil geometry verification, close loop with high flux (engineering mode).
Total duration: 25 days, daytime 20 days, nighttime 5 nights
FLAO system external review, Florence, 30/31 March 2009 7
Observing modes daytime & on sky test
On sky system performance vs. star mag, r0, v0: -engineering mode (baseline) -observing mode (ACE/ICE) (baseline) - ACE with on sky parameters optimization (goal)
[SR >= baseline performance (FLAO_06)]
Task summary: daytime fine calibration of system. Daytime closed loop test with verification of system performance in engineering and observing modes. On-sky test of system performance (both modes).
Total duration: 37 days, daytime 20 days, nighttime17 nights
FLAO system external review, Florence, 30/31 March 2009 8
Final on-sky FLAO test
SR better then baseline performance (FLAO_06):
Total duration: 14 days, nighttime14 nights
FLAO final test on sky:repetition of a specific set of tests already done in phase II (see FLAO_06)
Test list:Closed loop test with:
-Engineering mode-Observing modes

FLAO commissioning resuming table
The required manpower is found compatible with the available resources of the group. The group relevant personnel is composed by 17 persons. About 5-7 personnel units will be available in Arcetri to progress with FLAO#2 test in solar tower (13/01/10-06/07/10).
