MeDDEA, Measuring Directivity to Determine Electron Anisotropy, is one of the scientific instruments on the PADRE mission. It is a photon-counting hard X-ray directivity instrument that uses flight-spare detectors from the Spectrometer/Telescope for Imaging X-rays, STIX, provided by CEA-Saclay. MeDDEA measures individual photons and time-tags them with a time resolution better than 1 ms. The instrument has an energy range of approximately 3 keV to 110 keV and an energy resolution of approximately 1.1 keV at 59.5 keV. Its field of view is about 6 degrees, but it does not provide spatial resolution. MeDDEA is designed to investigate the directivity of solar flare X-ray emissions and to advance understanding of solar flare electron anisotropy.
