Nancy Grace Roman Space Telescope

The Nancy Grace Roman Space Telescope, formerly known as WFRIST, is a 2.4 meter-class space telescope that will be used across a swath of astro-physical research domains. JPL will provide a High Contrast Imaging Coronagraph - one of two major astronomical instruments.

In order to achieve the low noise performance required to detect planets under extremely low flux conditions, the Electron Multiplying CCD (EMCCD) has been baselined for both of the Coronagraph's sensors; the imaging camera and IFS. The Centre for Electronic Imaging are studying the impact of radiation damage on the detectors for the mission.
