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. </Description> <Contact> <PersonID>spase://CDPP/Person/Mats.Andre</PersonID> <Role>PrincipalInvestigator</Role> </Contact> <InformationURL> <Name>ESA web page</Name> <URL>http://sci.esa.int/jump.cfm?oid=33024</URL> <Description>EFW: Electric Field and Wave experiment</Description> </InformationURL> <InformationURL> <Name>NSSDC's Master Catalog</Name> <URL>http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=2000-045A&ex=8</URL> <Description>Information about the Electric Field and Waves (EFW) experiment on the Cluster 2/FM6 (Salsa) mission.</Description> </InformationURL> <PriorID>spase://SMWG/Instrument/Cluster2-Salsa/EFW</PriorID> </ResourceHeader> <InstrumentType>LongWire</InstrumentType> <InvestigationName></InvestigationName> <OperatingSpan> <StartDate>2000-12-01T00:00:00</StartDate> <Note>Start of full orbit coverage: 2002-06-01T00:00:00</Note> </OperatingSpan> <ObservatoryID>spase://CDPP/Observatory/AMDA/Cluster2</ObservatoryID> </Instrument> </Spase>
