This paper describes the status and details of the large synoptic survey telescope 1,2,3 mount assembly (TMA). On June 9 th , 2014 the contract for the design and build of the large synoptic survey telescope mount assembly (TMA) was awarded to GHESA Ingenieria y Tecnologia, S.A. and Asturfeito, S.A. The design successfully passed the preliminary design review on October 2, 2015 and the final design revi ew January 29, 2016. This paper describes the detailed design by subsystem, analytical model results, preparations being ta ken to complete the fabrication, and the transportation and installation plans to install the mount on Cerro Pachon in Chile. This large project is the culmination of work by many people and the authors would like to thank everyone that has contributed to th e success of this project. Keywords: LSST, telescope, mount, elevation, azimuth, linear drives, tape encoders, 1. INTRODUCTION The Large Synoptic Survey Telescope (LSST) is an 8.4-mete r wide-field (3.5-degree) survey telescope, which will be located on the summit of Cerro Pachon in Chile. The design of the telescope mount assembly is by GHESA Ingenieria y Tecnologia, S.A. Asturfeito, S.A, is fabricating the TMA in northern Spain is shall reinstall the mount on Cerro Pachon. The design of the mount control, camera cable wrap, and mirror covers is by IK4 Tekniker. The design and fabrication of the azimuth and elevation li near drives and capacitor bank is by Phase Motion Control. This telescope mount assembly supports the optics, camera, baffles, and the integral subsystems required to operate the telescope. This report provides an overview of the final design of the mount and all supporting subsystems. |
