The European ALMA prototype - High Precision Dish from Design up to On Site Alignment

摘要

The European ALMA antenna dish including Back-Up Structure, Panel Adjusters and Panels are designed and manufactured using high level technologies and innovative production processes. The On Site installation is performed thanks to high performances measurements and alignments processes, with short alignment duration. Special design features of the European ALMA antennas are described, Manufacturing mass production works are presented, Alignment methods defined.
