LBTI Program Management Review Phil Hinz S.H. (Hop) Bailey 2 December

Agenda 2

LBTI Summary (July – 10/14/14) TechnicalScheduleProgrammatic Overall On plan, adequate margin Problems, working to resolve within planned margin Problems, not enough margin to recover Resources 3 GYR 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 staff Programmatic 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 GGGY G

Action Items From Last PMR

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 5
