Particle Detectors
ULEIS
The Ultra Low Energy Isotope Spectrometer (ULEIS) on the Advanced Composition Explorer (ACE) measures ion fluxes over the charge range from He through Ni from about 20 keV/nucleon to 10 MeV/nucleon, thus covering both suprathermal and energetic particle energy ranges. Exploratory measurements of ultra-heavy species (mass range above Ni) will also be performed in a more limited energy range near 0.5 MeV/nucleon. ULEIS will be studying the elemental and isotopic composition of solar energetic particles, and the mechanisms by which these particles are energized in the solar corona. ULEIS will also investigate mechanisms by which supersonic interplanetary shock waves energize ions. ULEIS was designed and developed by ther Johns Hopkins Applied Physics Laboratory and the University of Maryland See: http://sd-www.jhuapl.edu/ACE/ULEIS/ Group: Instrument_Details Entry_ID: ULEIS Group: Instrument_Identification Instrument_Category: Solar/Space Observing Instruments Instrument_Class: Particle Detectors Short_Name: ULEIS Long_Name: Ultra Low Energy Isotope Spectrometer End_Group Group: Associated_Platforms Short_Name: ACE End_Group Online_Resource: http://sd-www.jhuapl.edu/ACE/ULEIS/ Sample_Image: http://sd-www.jhuapl.edu/ACE/ULEIS/pics/NEW_ULEISimage4x4.gif Group: Instrument_Logistics Data_Rate: 1 kbps Instrument_Start_Date: 1997-08-25 Instrument_Owner: Johns Hopkins University Applied Physics Lab End_Group End_Group
