Advancing FUV Spectroscopy on the Ground and In Space

Dr. Emily Witt

Abstract: Recent advances in far ultraviolet optical and spectroscopic technology are allowing new instrument designs capable of achieving the next generation of science observations. These new technologies include high reflectivity mirror coatings, geocoronal light suppression filters, and photon-counting detectors. In this talk I will discuss the Slitless Ultraviolet Spectrograph with Hydrogen rejection Instrument (SUSHI), a ground testbed to validate the use of thin film mirror coatings optimized for Lyman alpha (121.6 nm) rejection in a spectroscopic instrument. These coatings can then be considered for use on a flight platform such as the Juniper 16U CubeSat mission concept which aims to conduct a detailed study of the kinematics of the warm/hot gas in the CGM of nearby galaxies. Together, these instruments encompass technology development from the ground to space, advancing the technology readiness level of components key to the success of future large missions.
