HYDRA
type: Concept
definition: HYDRA is a plasma experimental investigation on the POLAR spacecraft. HYDRA is a collection of electrostatic analyzers designed for high resolution observations of electron and ion velocity distributions in the earth's polar magnetosphere and was designed and constructed by a consortium of institutions for the purpose of improving our understanding of the complex interactions of the polar magnetosphere with the solar wind and the ionosphere. HYDRA subsystems are: - Duo-Deca-Electron-Ion-Spectrometer (DDEIS) - Parallel Plate Analyzer (PPA) - Data Processing Unit (DPU) and UV Intracalibration System For more information, see: http://www-st.physics.uiowa.edu/ and http://pwg.gsfc.nasa.gov/polar/polar_inst.shtml Group: Instrument_Details Entry_ID: HYDRA Group: Instrument_Identification Instrument_Category: Solar/Space Observing Instruments Instrument_Class: Particle Detectors Short_Name: HYDRA Long_Name: Hot Plasma Analyzer End_Group Group: Associated_Platforms Short_Name: POLAR End_Group Online_Resource: http://www-st.physics.uiowa.edu/ Sample_Image: http://www-st.physics.uiowa.edu/www/images/ddeis2.jpg Group: Instrument_Logistics Instrument_Start_Date: 1996-02-24 Instrument_Owner: University of Iowa End_Group End_Group
