Abstract

The LSST Coating Plant consists of a Coating Chamber for high reflective optical coatings deposition and a Cleaning and Stripping Station for the M1M3 and M2 mirrors. The Coating Chamber sputtering process will be capable of depositing bare and protected Silver/Aluminum coating recipes. The Cleaning and Stripping Station consists of a rotating washing/drying boom, perimeter platforms, and an effluent handling system within the M1/M3 mirror cell. This paper describes the status of the Coating Plant construction effort at the Von Ardenne and MAN facilities. Progress on factory testing, review of the design features and reflective/coating requirements, and results are presented.
