Overview of Roman Coronagraph Instrument requirements, test campaign, and results
NASA’s Nancy Grace Roman Space Telescope includes the coronagraph instrument (CGI): a technology demonstrator for active coronagraphy that uses deformable mirrors for deep starlight suppression, which enables imaging and spectroscopy of nearby faint companions. We provide an overview of the instrument-level test campaign of the CGI that took place at the Jet Propulsion Laboratory prior to the delivery of this instrument for the Roman payload and observatory integration. This test campaign served to expose the instrument to the environments associated with the Roman launch and space operations and to verify the CGI functional and performance requirements in the most comprehensive way possible prior to launch. An overview of the coronagraph requirements and key results of the test campaign is presented.
