The Electron Drift Instrument
Abstract
The Electron Drift Instrument (EDI) measures both electric and magnetic fields by measuring the drift of an emitted and coded electron beam during one or more gyro-periods. This technique has been proven on both Equator-S and CLUSTER-II and is impervious to many interference sources around the spacecraft. In addition, the steer-able electron sensor can also be used as a very high geometric factor instrument to detect fast electron beams. This talk will describe the technique, comparisons with other measurement techniques on CLUSTER, and recent results using EDI.
