(ExEP) A new integral field spectrograph for broadband coronagraph demonstrations at the High Contrast Imaging Testbed Facility

An integral field spectrograph (IFS) camera may help fulfill the exoplanet characterization goals of a future Habitable Worlds Observatory. Here we present the design of a successor to the Prototype Imaging Spectrograph for Coronagraphic Exoplanet Studies (PISCES) that will interface with the laboratory coronagraph on the Decadal Survey Testbed 2 (DST2), located in the High Contrast Imaging Testbed 2 vacuum chamber at NASA's Jet Propulsion Laboratory. This new IFS camera will help to advance spectroscopy technology for the Habitable Worlds Observatory and support demonstrations of broadband wavefront sensing and control and data post-processing techniques.
