3 ESO is the focus of astronomy in Europe Key facts Facilities i ESO builds & operates several of the world s most advanced ground-based telescopes ESO is an intergovernmental organisation 14 member states Employs 661 staff Receives 164 M total annual contributions UK contributes around 20% Funded through the STFC Current - VLT Future ELT, ALMA The UK only joined ESO in 2002

4 Current Projects at ESO include the VLT, ALMA and the E-ELT VLT ALMA E-ELTELT The VLT is the world s ALMA will be a single mm E-ELT will be a nextgeneration most advanced visible & IR observatory Four 8.2m telescopes and sub-mm telescope. 66 antennas of up to 12m diameter IR & optical telescope. Segmented 42m primary Four movable 1.8m auxiliary telescopes Telescopes can be coupled as an interferometer Based at the Paranal Observatory (Chile) antennas movable over 16km distances ALMA is being built in an international i collaboration between ESO, US and Japan Construction phase underway (c. 1bn) mirror Adaptive optics on telescope & instruments Construction phase expected to start in 2012 Total budget c. 1bn

10 The E-ELT is an ambitious project Key Facts 42m diameter primary mirror 984 hexagonal segments 6m secondary mirror 4m tertiary mirror 2.6m adaptive M4 mirror 5000 tonne active support structure 100m enclosure Adaptive optics system 6 laser guide stars Two instrument platforms Tennis court sized Construction planned to start in Operational 2019

11 Segmented primary mirror is mounted on active support system Key Facts Primary mirror 42m diameter m hexagonal segments Support structure Whiffletree mount distributes load Active support Tip-tilt, piston, torsional 12 edge sensors per segment 20 nm rms alignment Control system 23,000 inputs 63,000 outputs

12 The M1 cell a 25M manufacturing opportunity Key Facts 27 point kinematic mirror mount Moving frame allows movement as rigid body in piston, tip, tilt Sub-cell drives piston, tip, tilt motion 1000 units ESO envisage a 25M contract single manufacturer for components 2013 to 2016

13 Additional optics include a large deformable mirror Secondary mirror 5.6m diameter 156 axial supports Tertiary mirror 4m diameter Key Facts Hexapods rack Mounting Structure M4 2.6m diameter Deformable with actuators Mounting Structure Hexapods M5 3 x 2.4m dimensions Tip-tilt adjustment Adaptive mirror Membrane & shells Light beam Electronics rack

15 The VLT construction relied on industry collaboration Schott Zeiss Linde Cegelec SEBIS Fokker TNO/TPD Ansaldo AES REOSC AMOS Skanska GIAT Dornier Collaboration with Industry has been a key factor for the success of the VLT

16 Case Study: E-ELT primary mirror segment polishing at OpTIC Glynd r Primary mirror segment polishing OpTIC submitted proposal for prototyping study of 7 primary mirror segments for ELT Won 5m contract in December 2007 Due for completion 2010 OpTIC are applying new technologies to demonstrate the fast polishing times necessary for mass production of optical surfaces The OPTIC-led consortium includes OpTIC, Qioptiq UK Ltd, Zeeko Ltd, IKC- UPS2 The consortium is well placed for securing a production contract worth approx. 200m
