Problems, not enough margin to recover

Technical• Successful and repeated nulling accomplished in CB2a (November runs). • Low-frequency vibration suppression successfully demonstrated under range of observing conditions• Engineering effort on LBT structures flagged by LBTO for future effort to determine source, structural modes and alternative mitigation;

modeling and accelerometer progress by both UA and JPL• Detector noise determined to be inherent in the detector• LBT secondaries performed nominally during CB2a demonstrating repairs in August continue to mitigate contact problems• LBTO/JPL worked technical solutions for long-term mitigation of AO electrical contact failures• LBTO preparing spare secondary shell• Successful CB2a showing improved nulling depth and repeatability. Fringe locking automation improved.

Schedule• UA updates the schedule weekly and reviews the result with JPL bi-monthly• LBTO conducts engineering runs prior to the CBs to demonstrate readiness of the Telescope systems (complete on CB2)Resources• Additional labor at JPL and UA, as well as funding and procurement of some spares, now in the plan• LBTO has hired an AO Engineer, Guido Brusa, to complement the current AO staffProgrammatic • ORR scheduled for Apr 16, 2015• Planning budgets submitted to JPL for FY15-18 including overguidance budget for extended science observations in FY18• Working detector array spare or alternative with ESO• LBTI PM assessment: Mitigated risk of meeting April 2015 ORR by 1) continued improvements in measured errors during CB2a, 2)

stability of provisional fix to LBT AO systems

Accomplishments• LBTI

– Successfully conducted CB2a• Acquired repeated successful nulling sequences• Demonstrated success of phase loop to suppress low-frequency

vibration

– Submitted cost proposal to JPL for spares procurement• LBTO

– Stable operation of all telescope systems in support of LBTI including AOs.

– Conducted closed-loop secondary engineering run prior to LBTI CB2s

– Hosted JPL team in Tucson to discuss spare AO shell and visit Sunnyside coating facility
