Paper Abstract

High spatial resolution thermal unsteady CFD simulations of LSST are performed and processed to provide image degradation due to dome seeing in FWHM. An analysis of the sensitivity of the image quality to certain important geometric features and aerothermal properties is presented. More specifically, the influence of the LSST vent light baffles and windscreen, the wind speed and the surface temperature of components such as the primary and secondary mirrors, the camera, the telescope structure and dome exterior is assessed and conclusions are drawn. The secondary mirror and camera surface temperatures are found to be among the most critical in minimizing LSST dome seeing.
