2.2.2 spase://SMWG/Instrument/Equator-S/SFD Scintillating Fiber Detector (SFD) SFD 2019-05-05T12:34:56Z SFD is based on the light emission property of some materials when hit by ionizing radiation. Optical fibres guide the emitted light to a photodiode operated in current mode. A logarithmic amplifier converts this detector current to an analog output voltage. Energy discrimination is achieved by using three differently shielded channels. This way electrons above 0.26, 0.4, and 1.9 MeV are measured, and protons above 6.3, 9.5, and 35 MeV, with a time resolution of 64 seconds. A constant current is added periodically to calibrate the system. spase://SMWG/Person/L.Adams PrincipalInvestigator NSSDC's Master Catalog https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=1997-075B-07 Information about the Scintillating Fiber Detector (SFD) experiment on the Equator-S mission.
