[PEM11-P23] PARM-HEP Observation of Precipitating High Energy Electrons over Pulsating Aurora
Keywords:Microburst, PARM, RockSat-XN, LAMP, Sounding rocket, Pulsating aurora
For that purpose, we have developed a high-energy electron detector (HEP) for the observation of sub-relativistic - relativistic energy electrons that make up the microburst. HEP is designed to measure electrons between 300 keV and 2 MeV with energy resolution of 20% or less and with signal processing time of ~ 5 μs. Energy analysis is performed by the detection part of this instrument using SSD (Solid State Detector). Performance tests of this instrument are carried out using a sealed radiation source and a high energy electron beam line. This instrument is installed as one of the core instruments of the PARM instrument package developed for the simultaneous observation of the pulsating aurora and microburst by an international student sounding rocket experiment RockSat-XN and LAMP (Loss through Auroral Microburst Pulsation) sounding rocket experiment. We have succeeded in obtaining the flight data on 13 January 2019 from RockSat-XN sounding rocket experiment. In parallel, we are now preparing HEP analyzer for LAMP sounding rocket experiment. In this presentation, we will show the outline and observation results of RockSat-XN-HEP as well as the LAMP-HEP development status.
