MATE consist of a 360° field-of-view sector magnet energy analyser with 90° deflection angle for simultaneous energy and + pitch angle determination. The sampling rate for the full energy range is 10 ms, and acollimator system enables measurements of the + energy spectrum at 16 energies , and 30 angular sectors. Unfortunately, the MATE instrument was not deployed completely and was to 1/3 + blocked by the Freja spacecraft itself and only every 4th angular sector have data. Also, the MATE instrument did only work properly up + to orbits around 1600, where after only the integrated flux of the high-energy electrons could be obtained. In addition, the lowest energy + channels was found to give uncertain data. + + The Two-dimensional Electron SPectrometer (TESP) on Freja consists of a "top-hat" style sweeping electrostatic analyser. The energy range + of 20-25 keV is covered in 32 sectors to complete a spectrum. Depending on instrument mode, 16 or 32 spectra are returned each second + (31.25 ms resolution). The angular field-of-view is the full 360° and electrons are counted in 32 equally spaced bins, yielding an angular + resolution of 11°. The entrance aperture of the TESP also contains a set of electrostatic deflectors which allows the plane of acceptance + to be "warped" into a cone. + The TESP experiment started working around orbit 720, when the instrument software were sent tot the spacecraft after the launch. The TESP + data covers only energies up to 25 keV, but gives nervertheless important information regarding the high-energy electrons. Since low energy + electrons may cause an excess emission of secondary electrons (and thereby mitigate charging), the information from this experiment is very + useful. Note that the energy channels below about 30 eV was found to give uncertain data.</Description> + <Contact> + <PersonID>spase://SMWG/Person/Manfred.H.Boehm</PersonID> + <Role>PrincipalInvestigator</Role> + </Contact> + <Contact> + <PersonID>spase://SMWG/Person/Jan-Erik.Wahlund</PersonID> + <Role>ProjectScientist</Role> + </Contact> + <InformationURL> + <Name>Technical Note</Name> + <URL>https://space.fmi.fi/spee/docs/wp110_tn1.pdf</URL> + </InformationURL> + </ResourceHeader> + <InstrumentType>Spectrometer</InstrumentType> + <InvestigationName/> + <OperatingSpan> + <StartDate>1992-11-03T00:00:00</StartDate> + <StopDate>1994-10-04T23:59:59</StopDate> + </OperatingSpan> + <ObservatoryID>spase://CNES/Observatory/CDPP-AMDA/Freja</ObservatoryID> + </Instrument> +</Spase> diff --git a/Instrument/CDPP-AMDA/FREJA/MFE.xml b/Instrument/CDPP-AMDA/FREJA/MFE.xml new file mode 100644 index 0000000..4094db6 --- /dev/null +++ b/Instrument/CDPP-AMDA/FREJA/MFE.xml @@ -0,0 +1,51 @@ +<?xml version="1.0" encoding="UTF-8"?> +<Spase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.spase-group.org/data/schema" xsi:schemaLocation="http://www.spase-group.org/data/schema http://amda.irap.omp.eu/public/schemas/spase-2_3_1.xsd"> + <Version>2.3.1</Version> + <Instrument> + <ResourceID>spase://CNES/Instrument/CDPP-AMDA/FREJA/MFE</ResourceID> + <ResourceHeader> + <ResourceName>MFE</ResourceName> + <AlternateName>Magnetic Field Experiment</AlternateName> + <ReleaseDate>2004-07-20T21:10:13Z</ReleaseDate> + <Description>The Swedish satellite, FREJA, was launched 6 October, 1992 into a 63 degree inclination, 600x1700 km altitude orbit. + The satellite is in the auroral zone a significant amount of the time. Ionospheric current systems are monitored by the Johns + Hopkins University Applied Physics Laboratory (JHU/APL) Magnetic Field Experiment (MFE). The MFE for the FREJA spacecraft was + provided as the only US principal experiment by the JHU/APL in cooperation with the NASA/Goddard Space Flight Center. + + The FREJA MFE includes a custom JHU/APL-designed Forth Reduced Instruction Set Computer (FRISC) microprocessor. The purpose of + the MFE computer is to allow extensive on board processing which has traditionally been performed after-the-fact on recorded data. + One of the many on board functions is an auroral zone field-aligned current detector patterned after the UARS MFE peak detector AC + channel. The 1.5 - 128 Hz bandpassed channel of the spin axis fluxgate magnetometer sensor is monitored by a one second standard + deviation calculation. When this result exceeds a programmable threshold (presently set at 100 nT) a trigger word is set which + circulates through the satellite telemetry system and can be used to initiate various experiment data taking. This MFE trigger value + is time-tagged, stored in the spacecraft housekeeping telemetry, and may be transmitted by an auxiliary, limited bandwidth transmitter + and received in near real time by a simple, portable antenna and receiver. The advantage of this detection approach is the simplicity + of the analysis and the direct, automatic and real time correlation with current systems previously determined by extensive ground + processing. This detector information can be received real-time or transferred via network or telephone from the receiving station + in Kiruna, Sweden using PC-based communications packages. </Description> + <Contact> + <PersonID>spase://SMWG/Person/Lars.Eliasson</PersonID> + <Role>GeneralContact</Role> + </Contact> + <Contact> + <PersonID>spase://SMWG/Person/L.J.Zanetti</PersonID> + <Role>ProjectScientist</Role> + </Contact> + <InformationURL> + <Name>Freja F3H data archive at IRF</Name> + <URL>http://www2.irf.se/program/sspt/Freja/</URL> + </InformationURL> + <InformationURL> + <Name>MF experiment webpage at JHUPL</Name> + <URL>http://sd-www.jhuapl.edu/Freja/</URL> + </InformationURL> + </ResourceHeader> + <InstrumentType>Magnetometer</InstrumentType> + <InvestigationName/> + <OperatingSpan> + <StartDate>1992-10-24T00:00:00</StartDate> + <StopDate>1995-02-15T23:59:59</StopDate> + </OperatingSpan> + <ObservatoryID>spase://CNES/Observatory/CDPP-AMDA/Freja</ObservatoryID> + </Instrument> +</Spase> diff --git a/NumericalData/CDPP-AMDA/FREJA/ESP/fja-sc-charg.xml b/NumericalData/CDPP-AMDA/FREJA/ESP/fja-sc-charg.xml new file mode 100644 index 0000000..9f6d372 --- /dev/null +++ b/NumericalData/CDPP-AMDA/FREJA/ESP/fja-sc-charg.xml @@ -0,0 +1,109 @@ +<?xml version="1.0" encoding="UTF-8"?> +<Spase xmlns="http://www.spase-group.org/data/schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.spase-group.org/data/schema http://amda.irap.omp.eu/public/schemas/spase-2_3_1.xsd"> + <Version>2.3.1</Version> + <NumericalData> + <ResourceID>spase://CNES/NumericalData/CDPP-AMDA/FREJA/ESP/fja-sc-charg</ResourceID> + <ResourceHeader> + <ResourceName>charging events</ResourceName> + <AlternateName></AlternateName> + <ReleaseDate>2004-02-22T01:49:00Z</ReleaseDate> + <Description>This dataset provides data of a total of 291 spacecraft surface charging events detected during the operation of the Freja satellite. + The dataset provides peak charging level, light conditions and charging duration. + The Freja mission objective was to study the polar (high latitude) auroral processes and was therefore + equipped with a highly advanced plasma payload package, and the spacecraft itself was designed to be + as electrically clean as possible.
