Geotail - LEP - editor B: ions

2020-08-16 22:33:50Z

12-second Editor-A low-energy particle data from the Geotail spacecraft.

        Editor-A data are only acquired with the real-time operation in Usuda Deep Space Center (UDSC),Japan, while the Editor-B data are 24-hours continuouslyrecorded in the onboard tape recorders and are dumpedover the NASA/JPL Deep Space Network (DSN) stations.

        The ion energy analyzer (LEP-EAi) has two energy scan mode: RAM-A (60 eV to 40 keV) and RAM-B (5 keV to 40 keV). RAM-B is selected to protect the very sensitive detector from intense low energy fluxes that are usually seen in the solar wind and magnetosheath. The energy scan mode is automatically selected onboard depending on incoming ion fluxes. At present, only the ion moments in the RAM-A mode are listed for the LEP-EAi data.

        The ion moment data of the solar wind analyzer (LEP-SW) should be used only qualitatively. The LEP-SW ion moments are listed when the energy scan mode of LEP-EAi is RAM-B. 
        CPI/SWEA and LEP measurement are expected to be used in a complementary way. LEP is highly sensitive and is dedicated to measure 
        tenuous plasma of the magnetosphere. However, when GEOTAIL is in the interplanetary, LEP generally  scans only the high energy 
        (> 5 KeV) part of the ion distribution. This automated mode allows to assure long term preservation of the LEP detectors. 
        The LEP ion moments obtained in the inteerplanetary medium should be used only for qualitative purposes. 
        The ion moments in the interplanetary medium are provided by the CPI/SWEA instrument designed for measuring the denser 
        magnetosheath and solar wind plasma.

In any publications, the use of the Geotail data should be acknowledged, for example, as "Geotail magnetic field data were provided by Y. Saito, JAXA in Japan."
