摘要 中能电子测量对空间辐射环境的理论研究和空间航天器的防护设计具有重要意义。北京大学研制的中能电子成像谱仪(BD-IES)利用小孔成像技术实现多方向中能电子的能谱测量。地面标定试验结果表明,BD-IES具有良好的能量线性度和较小的系统噪声,能够有效实现对中能电子的能谱测量。该仪器已成功应用在我国导航卫星上。最新测量结果表明BD-IES对中能电子的测量是成功的,其结果对于研究如亚暴注入、波-粒子相互作用等空间物理热点问题具有重要意义。BD-IES未来将被应用到"风云"等空间环境探测平台上。 The observation of energetic electrons is important for studies of the space radiation environment and the design of spacecraft.The Imaging Electron Spectrometer developed by Peking University(BD-IES)is based on the pin-hole imaging technique and the Si-PIN position sensitive detector,which can measure the spectra of the energetic electrons in multi-directions.The results of the ground calibration tests show that the BDIES has a good energy linearity and small system noise,which can measure the spectrum of energetic electrons effectively.The BD-IES is successfully deployed onboard a Chinese navigation satellite in the inclined GEO orbit.The latest observation verifies that the energetic electron observation of the BD-IES is successful,which is important for studies of space physics,such as the sub-storm injection,and the wave particle interaction,etc.
