LUVOIR is one of the four large missions being studied for the Astro 2020 decadal review. The LUVOIR observatory is a large, ~9-15m diameter, serviceable concept. The observatory must be highly stable, low 10’s of picometers/10s of minutes and has cold, less than 100K detectors, and warm mirrors, 270K. This paper discusses the evolution of the thermal architecture and discusses the trades evaluated to arrive at the current concept. The next steps in the development will be discussed.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
