Paper Abstract

The former Advanced Technology Solar Telescope (ATST), now renamed to Daniel K. Inouye Solar Telescope (DKIST) will be the largest solar telescope in the world – with a 4m aperture primary mirror and a 16m diameter co-rotating “Coudé” laboratory located within the telescope pier. Both, the telescope mount and the Coudé laboratory use for their azimuth axis a new kind of bearing technology, so called R-guides, which minimize later maintenance efforts, avoid energy consumption and the risk of oil spill of conventional hydrostatic bearings. The paper describes the integrated modeling approach for the verification of the challenging DKIST jitter requirement of 0.075 arcsec rms with the new bearing system, including initial system engineering guidelines, finite element evaluations, system dynamics and end-to-end jitter simulations, factory tests of subsystems and components, and the commissioning of the trial assembled Coudé table and later the telescope mount.
