  1. Contacts Dr. Norbert Hubin OPTICON JRA1 Coordinator European Southern Observatory Karl Schwarzschild Str. 2 Garching, Germany Telephone: +49 89 320 06 517 E-mail: nhubin@eso.org Dr. John K. Davies OPTICON Project Scientist UK Astronomy Technology Centre, Blackford Hill, Edinburgh, EH9 3HJ United Kingdom Telephone: +44 (0)131668 8348 E-mail: jkd@roe.ac.uk Web: www.astro-opticon.org INSU ETH Zurich OPTICON - The Optical Infrared Coordination Network for Astronomy JRA-1 - Adaptive Optics 1370 piezo actuator Deformable Mirror The development of this DM is the largest worldwide. It is an essential component for the VLT Extreme AO system and Ground Layer AO. JRA 1 gathers together expert European teams in the field of Adaptive Optics for astronomy. It has two objectives. 1) Develop the concept and designs for 2nd generation Adaptive Optics facilities (e.g Extreme Adaptive Optics for Planet Searching, Ground Layer and Multi-Conjugate Adaptive Optics) which by 2010-11 will equip existing 8-10 m telescopes such as the VLT, the LBT and the GTC. 2) Develop the key technologies necessary to maintain the competitiveness of our large astronomical facilities. The 2nd generation AO Facilities • The enabling technologies • JRA-1 has an aggressive R&D programme: • 1m large Deformable Mirror (DM)& very thin glass shell demonstration • VLT Ground Layer & tomography AO 1.1m VLT Adaptive secondary (Microgate - ADS, Italy) equipped with 1170 actuators and an hexapod essential for the GLAO system using laser tomography. Thin Glass shell • VLT Extreme AO for Planet search • Participants: • European Southern Observatory • INAF Arcetri • MPIA Heidelberg • INSU-LAOG and LAM • ONERA • NOVA • Univ. Durham • High Order wavefront sensing exp.: • Multi-Conjugate AO for LBT: • Ground Layer wavefront sensor design • Micro Deformable Mirror (MDM) • 60 electromagnetic actuator MDM (Patent) • 19 actuator electrostatic MDM OPTICON is funded by the European Commission under Contract RII3-CT-2004-001566
