  2. The Telescope and Site Team has developed an Observatory System to perform the LSST Mission Summit Facility Controls Survey Captures Light Calibrates Conditions 30-m Dome 350-ton Telescope 1.2-m Atmospheric Telescope 1,380m2 Service and Maintenance Facility Camera Clean Room Control Room Coating Chamber Base Facility Operations Support Data Access Center

  3. The Dome System 04C.04 Dome - Scope of Subsystem The Dome is the upper rotating portion of the Telescope Building. It provides the environmental protection of the telescope from the elements during the day. It has an observing aperture that operates to allow the telescope to view the night sky, rotating and maneuvering to keep the aperture in line with the telescope pointing, while shielding the telescope from stray light and excessive wind. The Dome includes the structural and sealing elements, the vents for natural flow of air through the telescope enclosure at night and the drive and control systems to provide the necessary motions.

  4. Numerous design shapes analyzed during the development cycle • Roll-off/retracting design rejected due to stray light • Rectangular too inefficient; Calotte deemed too risky • Final comparison of carousel vs. spherical • Carousel design chosen after analysis • Simplified fabrication/erection & cost effective • Better dome ventilation

  5. Baseline design sized to safely support all handling operations via 20-ton crane Overhead crane is required to remove & install M1M3 mirror cover for transport to & from coating chamber. M1M3 Mirror Cell on Cart with cover above

  6. Design improvements included after discussions with potential vendors • Camera removal similar to VISTA instrument procedure • Remove through back doors to maintain aperture integrity

  7. Dome system to be procured via fixed price design/build contract • Design review May 20-21 • RFP in July • Award in late 2014 • Design review cycles in SOW • Performance specification • Merge contract into PMCS shedule
