[PEM13-P05] PARM-HEP Observation of Microburst Precipitation over Pulsating Aurora
Keywords:microburst, sounding rocket, PARM, pitch angle scattering, 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. 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 the 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. Since the rocket was unfortunately launched on the dayside under quiet condition, simultaneous observation with pulsating aurora was impossible and the significant microbursts cannot be detected, but we detect quasi-relativistic energy electrons that can be explained by pitch angle scattering by weak chorus waves in the quiet dayside magnetosphere. On the other hand, LAMP rocket experiments are prepared for launch in winter 2020. We load an anti-coincidence counter on HEP mounted on LAMP to eliminate the effects of penetrating particles such as galactic cosmic rays. In this presentation, we will show the outline and observation results of HEP as well as the current status of the preparation for the launch of LAMP.
