Goals: * Determine SEP input into the atmosphere as a function of altitude * Determine SEP heating, ionization, and sputtering of upper atmosphere * Detect the highest energy pickup ions (>30 to 100s of keV) Observations: * Characterize solar particles in an energy range that affects upper atmosphere and ionospheric processes (~120 – 200 km) * Time resolution adequate to capture major SEP events ( less 1 hour) Technical details and heritage: * Two dual double-ended telescopes * Four look directions per species, optimized for parallel and perpendicular Parker Spiral viewing * Protons and heavier ions from ~25 keV to 12 MeV * Electrons from ~25 keV to 1 MeV * Energy fluxes 10 to 106 eV/cm2-sec-ster-eV * Better than 50% energy resolution * Heritage from (nearly identical to) SST on THEMIS </Description> <Contact> <PersonID>spase://SMWG/Person/Davin.Larson</PersonID> <Role>PrincipalInvestigator</Role> </Contact> <InformationURL> <Name>SEP web page, Summary sheet </Name> <URL>http://lasp.colorado.edu/home/maven/science/instrument-package/sep/</URL> </InformationURL> </ResourceHeader> <InstrumentType>ParticleDetector</InstrumentType> <InvestigationName></InvestigationName> <OperatingSpan> <StartDate>2013-11-18T13:28:00</StartDate> <!--StopDate>2014-12-16T00:00:00</StopDate--> <!-- Note : Mission phases : multiple tags possible --> <Note>Mars arrival : 2014-09-28T19:24:00</Note> </OperatingSpan> <ObservatoryID>spase://CDPP/Observatory/AMDA/MAVEN</ObservatoryID> </Instrument> </Spase>
