Paper Abstract

The Large Synoptic Survey Telescope (LSST) Project1 received its construction authorization from the National Science Foundation in August 2014. The LSST Telescope and Site (T and S) group has achieved significant progress in the development and delivery of an integrated telescope system solution to meet the LSST science mission requirements. The summit facility construction has been completed on Cerro Pachón in Chile, construction of the base facility and data center continues in La Serena, and many major vendor subsystem integration and verification efforts are currently in progress. This paper summarizes the status of the T and S group, which is responsible to provide the summit and base facilities and infrastructure necessary to support the wide, fast, deep LSST survey mission. The major elements of the telescope system are well into factory assembly and testing, in anticipation of shipping, integration and final acceptance testing and verification on the summit. Progress continues on the dome system assembly atop the lower enclosure of the summit facility. The M1M3 primary/tertiary and M2 secondary mirror assembly systems are undergoing integrated system testing prior to shipment to Chile. Factory testing has been achieved on the telescope mount assembly, hexapod and rotator systems, coating plant, and the auxiliary calibration telescope. Other in-house efforts including software for observatory supervisory functions, scheduling of the survey, and active optics control has also advanced. The summary status of these subsystems and future integration and verification plans are presented.
