Interferometry in FP 7 Andreas Quirrenbach Alain Chelli Edinburgh, June 2006 13

Top-Level Goals Ø Build on success of FP 6 Ø Exploit current instrumentation to the fullest • Networking (exchange visits, working groups) • User-friendly data reduction and analysis tools Ø Support advances in VLTI instrumentation • 2 nd and 3 rd generation instruments Ø Prepare next-generation ground-based facility • Build science case • Conceptual design options • Develop critical technologies Ø Support space-based interferometry • Nulling technology • General science potential Edinburgh, June 2006 14

Proposed FP 7 Networking Activities Ø Fizeau Exchange Visitors Program Ø WG on science case for next-generation interferometer Ø WG on potential of Antarctica for interferometry (link with ARENA) Ø WG on Darwin science preparation Ø WGs on Interferometry and astrophysics • E. g. , asteroseismology, radiative transfer, fundamental stellar parameters Ø WG on VLTI instruments Ø Conference series: Applications of interferometry to astrophysics Edinburgh, June 2006 15

Proposed FP 7 JRA Activities (1 of 2) Ø Advanced user-friendly data reduction software Ø Second-generation data processing for VLTI Ø Optimized fringe tracking Ø Contribution to 2 nd-generation VLTI instruments (? ) Ø Studies of 3 rd-generation VLTI instruments Edinburgh, June 2006 16

Proposed FP 7 JRA Activities (2 of 2) Ø Guided optics (fibers, integrated optics) Ø Nulling technology (link with ESA) Ø Detectors (single-pixel, energy resolution) Ø Multi-beam co-phasing Ø Array design concepts Ø Beam transport concepts Ø Beam combination technology Ø Interferometer end-to-end modeling Edinburgh, June 2006 17

JRA Deliverables Ø Fully operational user-friendly software packages Ø Prototypes for key technologies (guided optics, nuller, single-pixel detector) Ø Realistic conceptual design(s) of nextgeneration interferometer Edinburgh, June 2006 18

Indicative Budget Ø Networking activities: Ø Software & algorithms: Ø Key technology development: Ø Next gen. conceptual design: Ø Post 2 nd gen. VLTI instruments: € 775, 000 € 1, 200, 000 € 1, 800, 000 € 850, 000 € 500, 000 Ø Grand total: € 5, 125, 000 Ø EU Funding only; cost-sharing not included Edinburgh, June 2006 19

Principal Interfaces Ø ESO (VLTI) and ESA (Darwin) • Leave programmatics to ESO/ESA • Support community and science cases Ø ELTs • Technology synergies (co-phasing, mirror and telescope manufacturing, …) Ø ARENA (Interferometry in Antarctica) • Through dedicated network • Deal mostly with specifics for interferometry • Leave specifics of Antarctica for ARENA Ø High-Time-Resolution JRA • Specialized detectors (few pixels, energy resolution) Edinburgh, June 2006 20

Activities outside OPTICON Ø Summer School Series • Marie Curie Program Ø Large Ground-Based Interferometer design study • • Preparation in FP 6/FP 7 Coordination with US (Decadal Review), others Timing depending on FP 7 funding opportunities Would seek OPTICON endorsement Edinburgh, June 2006 21

Programmatic Questions Ø Number of participants in FP 6 is large • Success! Many groups are contributing, interferometric community is growing • Management is difficult, accounting is tedious and expensive Ø Preparation of next-generation facility • Design-study proposal to FP 7 • Need to be ready in 2008 (? ) – which level of maturity is required? • Relation to roadmaps (ESFRI, Astronet) • Interface with OPTICON activities Edinburgh, June 2006 22
