Vector Electric Field Instrument (VEFI)

NSSDCA ID: 2008-017A-02

Mission Name: C/NOFS
Principal Investigator:Dr. Robert F. Pfaff


The Vector Electric Field Instrument (VEFI) consists primarily of three orthogonal 20m tip-to-tip double probe antennas. It measures the AC and DC electric fields related to plasma drift and irregularity development. The VEFI insturment package also includes a fluxgate magnetometer, a optical lightning detector and a fixed-bias Langmuir probe.
