2.3.1 spase://CNES/Instrument/CDPP-AMDA/Cluster4/EFW EFW Electric Field and Waves 2016-11-04T15:37:46Z The EFW (Electric Field and Waves) instrument consists of four orthogonal spherical sensors deployed from 50 m cable booms in the spin plane of the spacecraft, plus four deployment units and a main electronics unit. Each deployment unit deploys a multiconductor cable and tip-mounted spherical sensor. Each opposing pair of cables will be symmetrically deployed to a tip-to-tip distance of approximately 100 m, except for about a week at the beginning of the mission when 70 m will be used for one boom pair (the Z-booms) and 100 m for the other pair. The potentials of the spherical sensor and nearby conductors are controlled by the microprocessor to minimize errors associated with photoelectron fluxes to and from the spheres. spase://CNES/Person/Mats.Andre PrincipalInvestigator ESA web page http://sci.esa.int/jump.cfm?oid=33024 EFW: Electric Field and Wave experiment NSSDC's Master Catalog http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=2000-045A&ex=8 Information about the Electric Field and Waves (EFW) experiment on the Cluster 2/FM8 (Tango) mission. spase://SMWG/Instrument/Cluster2-Tango/EFW LongWire 2000-12-01T00:00:00 Start of full orbit coverage: 2002-06-01T00:00:00 spase://CNES/Observatory/CDPP-AMDA/Cluster4
