November 5, 2019 - This video captures an energizing milestone: the LSST Dome is moving! A team from EIE Group and Phase Motion Control was on the Summit from October 21 through 25 to start up and test the LSST Dome azimuth drives. The bogies (the assemblies of axles and wheels on which the dome rotates) were aligned, and the drives that power the dome were installed and connected.
During Operations, the LSST Dome will be powered by a rack-and-pinion system. The provisional friction-drive system which has now been implemented is being used for initial rotation to allow the positioning of the dome aperture, and to allow use of the interior crane as required for Telescope Mount installation.
