AURA New Initiatives Office Segment Fabrication Workshop I Tucson, Arizona May 30-31, 2002

Introduction

The AURA New Initiatives Office hosted a Workshop on Cost-Effective Fabrication of Mirror Segments, on May 30-31, 2002, in Tucson, Arizona.  The workshop brought together groups working on designs for Extremely Large Telescopes and potential mirror segment suppliers.  The main goals of the meeting were:

• To obtain advice from large optics finishers on cost-effective methods for producing large quantities of off-axis aspheric segments.
• To identify studies or other initiatives that can serve the interests of multiple ELT programs by improving understanding of key technical issues, and/or by advancing optical fabrication techniques
• To form collaborations to conduct and/or fund such studies.
