2.2.6 spase://SMWG/Instrument/MMS/2/FIELDS/EDI MMS 2 FIELDS Suite, Electron Drift Instrument (EDI) MMS 2 FIELDS Suite, EDI 2021-07-20T13:41:27Z Electron Drift Instrument (EDI) determines the electric and magnetic fields by measuring the drift of ~1 keV electrons emitted from the Gun Detector Unit (GDU). Each GDU sends (receives) a coded beam to (from) the other EDI-GDU. The EDI gun is being developed at the Institut fuer Weltraumforschung of the Austrian Academy of Sciences; EDI optics are being developed at the University of Iowa. It is part of the fields investigation which is led by Co-I R. B. Torbert (University of New Hampshire). spase://SMWG/Person/James.L.Burch PrincipalInvestigator spase://SMWG/Person/Roy.B.Torbert CoInvestigator Mission instrument web page https://www.nasa.gov/mission_pages/mms/spacecraft/mms-instruments.html Mission web page that describes the payload (instruments) on each spacecraft.
