Abstract

The High-energy Particle Detector (HEPD) on board the China Seismo-Electromagnetic Satellite (CSES-01)—launched on 2018 February 2—is a light and compact payload suitable for measuring electrons (3–100 MeV), protons (30–250 MeV), and light nuclei (up to a few hundreds of MeV). The Sun-synchronous orbit and large acceptance allow HEPD to measure cosmic-ray particles near the ±65° latitude limit for a fair amount of time per day. In this work, three semiannual galactic hydrogen energy spectra between ∼40 and 250 MeV are presented, including a comparison with theoretical spectra from HelMod, a 2D Monte Carlo model developed to simulate the solar modulation of cosmic rays throughout the heliosphere. To our knowledge, these are the first hydrogen energy spectra below 250 MeV measured at 1 au between 2018 and 2020. [ABSTRACT FROM AUTHOR]

Abstract

On 25 August 2018, a G3-class geomagnetic storm reached the Earth’s magnetosphere, causing a transient rearrangement of the charged particle environment around the planet, which was detected by the High-Energy Particle Detector (HEPD) on board the China Seismo-Electromagnetic Satellite (CSES-01). We found that the count rates of electrons in the MeV range were characterized by a depletion during the storm’s main phase and a clear enhancement during the recovery caused by large substorm activity, with the key role played by auroral processes mapped into the outer belt. A post-storm rate increase was localized at L-shells immediately above ∼3 and mostly driven by non-adiabatic local acceleration caused by possible resonant interaction with low-frequency magnetospheric waves.

Abstract

CSES (China Seismo-Electromagnetic Satellite) is a Chinese–Italian scientific space mission dedicated to monitor the variations of the main parameters of the topside ionosphere (electric and magnetic fields, plasma parameters, charge particle fluxes) caused by either natural emitters – especially earthquakes – or artificial ones. The CSES satellite was successfully launched from the Jiuquan Satellite Launch Center located in the west of Inner Mongolia on February 2nd, 2018, and it is now orbiting under nominal conditions. The expected mission lifetime amounts to 5 years. CSES is the first element of a multi-satellite monitoring system; several satellites are scheduled for the next few years. The High-Energy Particle Detector (HEPD) is the main contribution of the Italian collaboration to the mission. It was designed and built in order to detect electrons in the energy range between 3 and 100 MeV, protons between 30 and 200 MeV, and light nuclei in the MeV energy window. The electronics of the detector was designed following stringent requirements on mechanical and thermal stability, power consumption, radiation hardness and double redundancy. The system successfully went through the space qualification tests. In this paper, we describe the HEPD electronics, the space qualification tests performed before launch, and the in-flight performance of the detector. [ABSTRACT FROM AUTHOR]

Abstract

CSES (China Seismo-Electromagnetic Satellite) is a Chinese-Italian space mission dedicated to monitoring of variations of the electromagnetic field and waves, plasma parameters, and particle fluxes induced by natural sources and artificial emitters in the near-Earth space. The satellite was launched from the Jiuquan Satellite Launch Center in the Gobi desert (Inner Mongolia, China) on 2, 2018. The expected mission lifetime amounts to 5 years. The Italian contribution to the mission includes the design and construction of the High-Energy Particle Detector (HEPD), aimed to detect electrons in the energy range between 3 and 100 MeV and protons between 30 and 200 MeV, as well as light nuclei in the MeV energy range. In this paper, we describe the calibration procedures applied to HEPD based on data acquired during two tests at accelerator laboratories, which were performed on HEPD Flight Model prior to the delivery to China for final integration. An additional acquisition of cosmic muons was performed in order to better characterize the detector response before launch. [ABSTRACT FROM AUTHOR]

Abstract

CSES-01 (China Seismo-Electromagnetic Satellite) is a space mission dedicated to the study of the ionospheric environment, searching for disturbances that can be correlated to seismic activity. For this reason, the satellite is equipped with several instruments to monitor various physical parameters including the Earth's electric and magnetic field, ionospheric plasma principal parameters (i.e. density, temperature, and ions composition) and high energy particle flux fluctuations. The High Energy Particle Detector (HEPD), built by the Italian CSES-Limadou collaboration, is designed to detect mostly electrons in the energy range between 3 MeV and 100 MeV and protons in the energy range between 30 MeV and 300 MeV. The detector is composed of a tracking system, a segmented layer of plastic scintillator (used for the trigger), a range calorimeter and a veto system. After CSES-01 launch (February 2, 2018), the apparatus underwent the commissioning phase where its configuration was adjusted in order to guarantee optimal operational conditions in the space environment. Now the satellite is in stable data-taking mode. In this work a description of the HEPD detector will be reported, focusing on the results of the electron and proton test beam calibrations. In addition, a particular relevance will be given to the presentation of the HEPD in-flight performance, such as its good capability in particle identification. The high statistic collected by HEPD, thanks to its large acceptance window, makes it perfectly suitable for the investigation of fluctuations in the charged particle fluxes.

Abstract

CSES-01 (China Seismo-Electromagnetic Satellite) is a mission developed by CNSA (Chinese National Space Administration) and ASI (Italian Space Agency) to investigate the near-Earth electromagnetic, plasma and particle environment, focusing on the disturbances of the ionosphere-magnetosphere transition region. In this framework, the Italian High Energy Particle Detector (HEPD) on board CSES-01, is an advanced detector based on a tower of scintillators and a silicon tracker that provide good energy resolution as well as a wide angular acceptance for electrons of 3-100 MeV, protons of 30-200 MeV and light nuclei (up to Oxygen). The very good capabilities in both detection and discrimination of particles make the detector well suited for space-weather purposes; indeed HEPD is able to continuously monitor the magnetospheric environment with high precision and stability in time. Turbulent conditions in the near-Earth environment translate into modification of particles and magnetic/electric measurements at different time-scales. In this work, the data-analysis techniques and some preliminary results concerning the study of different proton populations encountered along CSES-01 orbit (galactic cosmic rays, re-entrant albedo etc.) are presented.
