The sealed proportional counter had a collimator and was sensitive to X rays from 1.5 to 20.2 keV. The CDTE detectors had discriminators that provided threshold values of 15, 30, 60, and 90 keV. The investigation was primarily concerned with X rays produced in the atmosphere by precipitating electrons. \n\n\nGroup: Instrument_Details\n Entry_ID: SSB/O\n Group: Instrument_Identification\n Instrument_Category: Solar/Space Observing Instruments\n Instrument_Class: Particle Detectors\n Short_Name: SSB/O\n Long_Name: Remote X-Ray Sensor - Precipitating Electrons (SSB/O)\n End_Group\n Group: Associated_Platforms\n Short_Name: DMSP 5D-1/F2\n End_Group\n Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/experimentDisplay.do?id=1977-044A-06\n Creation_Date: 2008-09-25\n Group: Instrument_Logistics\n Instrument_Owner: Department of Defense-Department of the Air Force (United States)\n End_Group\nEnd_Group"@en . <https://gcmd.earthdata.nasa.gov/kms/concept/3a099bab-607d-486a-9abd-43ea9be2122d> <http://www.w3.org/2004/02/skos/core#inScheme> <https://gcmd.earthdata.nasa.gov/kms/concepts/concept_scheme/instruments> . <https://gcmd.earthdata.nasa.gov/kms/concept/3a099bab-607d-486a-9abd-43ea9be2122d> <http://www.w3.org/2004/02/skos/core#broader> <https://gcmd.earthdata.nasa.gov/kms/concept/5f5e4f2c-61b7-4694-8680-3fc5799f6171> . <https://gcmd.earthdata.nasa.gov/kms/concept/3a099bab-607d-486a-9abd-43ea9be2122d> <http://data.bioontology.org/metadata/def/mappingSameURI> <https://gcmd.earthdata.nasa.gov/kms/concept/3a099bab-607d-486a-9abd-43ea9be2122d> . <https://gcmd.earthdata.nasa.gov/kms/concept/5f5e4f2c-61b7-4694-8680-3fc5799f6171> <http://www.w3.org/2004/02/skos/core#narrower> <https://gcmd.earthdata.nasa.gov/kms/concept/3a099bab-607d-486a-9abd-43ea9be2122d> .
