Abstract

The Off-plane Grating Rocket Experiment (OGRE) is a sounding rocket mission which aims to raise the technology readiness levels of three new technologies for soft X-ray astronomy, as well as produce the highest resolution spectrum of Capella yet. This paper focusses on the focal plane camera of the telescope which employs four electron-multiplying CCDs - three for spectral observations and one for imaging observations. The camera and its detectors will switch between two different operating modes during the observation window to maximise the scientific return of the mission, all while transmitting live telemetry and a limited amount of imagery data to the ground in real time. The energy resolution of the detectors has been modelled across the intended operational energy range to confirm whether diffraction orders can be separated, and the dependency of the multiplication gain on voltage and temperature has been characterised for each detector.
