  skos:definition """The Electron Drift Instrument (EDI) on Cluster-II measures the drift of a weak
beam of test electrons, from which the ambient electric fields and magnetic
field gradients can be determined. As a by-product, the magnetic field strength
is also measured.

EDI is a collaborative effort between the Max-Planck-Institut fur
extraterrestrische Physik (MPE) the  University of New Hampshire (UNH), and the
University of California San Diego (UCSD).

MPEs contribution was supported by  Deutsches Zentrum fur Luft- und Raumfahrt
(DLR) under grant 50 OC 9705.
