2.0.0 spase://SMWG/Instrument/ISEE1/UCB ISEE 1 UCB Particle Detectors 2019-05-05T12:34:56Z This experiment was designed to determine, by using identical instrumentation (see 77-102B) on the mother/daughter spacecraft, the spatial extent, propagation velocity, and temporal behavior of a wide variety of particle phenomena. Electrons were measured at 2 and 6 keV and in two bands: 8 to 200 keV and 30 to 200 keV. Protons were measured at 2 and 6 keV and in three bands: 8 to 200 keV, 30 to 200 keV, and 200 to 380 keV. The 30 keV threshold could be commanded to 15 or 60 keV. Identical instrumentation on each spacecraft consisted of a pair of surface-barrier semiconductor-detector telescopes (one with a foil and one without a foil) and four fixed-voltage cylindrical electrostatic analyzers (two for electrons and two for protons). Channel multipliers were used as detectors with the fixed-voltage analyzers. The telescopes had a viewing cone with a 40-deg half-angle, oriented at about 20 deg to the spin axis. spase://SMWG/Person/Kinsey.A.Anderson PrincipalInvestigator NSSDC Master Catalog https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=1977-102A-10 spase://nssdc/instrument/1977-102A-10 ElectrostaticAnalyser Electron and Proton Fluxes in the Outer magnetosphere spase://SMWG/Observatory/ISEE1
