摘要:

本文报告了搭载于中国地震电磁卫星(CSES-01)上的高能粒子探测器(HEPD-01)对五个强伽马射线暴(GRBs)的探测结果。CSES-01自2018年起在约507公里高度、97°倾角的太阳同步极轨道上运行。HEPD-01设计用于探测3 - 100 MeV能段的高能电子、30 - 300 MeV能段的质子以及30 - 300 MeV/n的轻核。尽管如此,蒙特卡罗模拟表明,HEPD-01对300 keV - 50 MeV能段的伽马射线光子敏感,尽管在约5 MeV以上具有适中的有效面积。对文献报告的GRBs与一组HEPD-01触发配置掩码信号进行的专门时间相关性分析,证实了探测器对高能光子的预期灵敏度。对GRB190114C、GRB190305A、GRB190928A、GRB200826B和GRB211211A的HEPD-01电子通量与光子的同时时间剖面比较显示,尽管能段不同,但两者具有显著的相似性。探测器在实际飞行配置下约2 MeV的峰值灵敏度以及适中的有效面积解释了为何这五个在300 keV - 50 MeV能段内总辐射通量超过约3 × 10^-5 erg cm^-2的GRBs被探测到。

英文摘要:

In this paper we report the detection of five strong Gamma-Ray Bursts (GRBs) by the High-Energy Particle Detector (HEPD-01) mounted on board the China Seismo-Electromagnetic Satellite (CSES-01), operational since 2018 on a Sun-synchronous polar orbit at a $\sim$ 507 km altitude and 97$^\circ$ inclination. HEPD-01 was designed to detect high-energy electrons in the energy range 3 - 100 MeV, protons in the range 30 - 300 MeV, and light nuclei in the range 30 - 300 MeV/n. Nonetheless, Monte Carlo simulations have shown HEPD-01 is sensitive to gamma-ray photons in the energy range 300 keV - 50 MeV, even if with a moderate effective area above $\sim$ 5 MeV. A dedicated time correlation analysis between GRBs reported in literature and signals from a set of HEPD-01 trigger configuration masks has confirmed the anticipated detector sensitivity to high-energy photons. A comparison between the simultaneous time profiles of HEPD-01 electron fluxes and photons from GRB190114C, GRB190305A, GRB190928A, GRB200826B and GRB211211A has shown a remarkable similarity, in spite of the different energy ranges. The high-energy response, with peak sensitivity at about 2 MeV, and moderate effective area of the detector in the actual flight configuration explain why these five GRBs, characterised by a fluence above $\sim$ 3 $\times$ 10$^{-5}$ erg cm$^{-2}$ in the energy interval 300 keV - 50 MeV, have been detected.
