The energetic particle detector on China's space station can determine the energy, flux, and direction of medium-and highenergy protons, electrons, heavy ions, and neutrons within the path of the station's orbit. It also assesses the linear energy transfer(LET)spectra and radiation dose rates generated by these particles. Neutron detection is a significant component of this work, utilizing a new type of Cs_(2)LiYCl_(6): Ce scintillator material along with plastic scintillators as sensors. In-orbit testing has demonstrated the efficient identification of space neutrons and gamma rays(n/γ). This data plays a crucial role in supporting manned space engineering, scientific research, and other related fields.

Lightning-generated whistler(LGW) is an important electromagnetic wave in the magnetosphere, causing energetic electron losses. Here we analyze the LGW distribution and propagation using Van Allen Probes data and ray-tracing *** statistics show that LGW occurs more frequently at Lspace as the wave power decays. The wave normal angle distributions indicate that LGW propagates quasi-parallel to the field line near its source and becomes oblique as the magnetic latitude decreases. Furthermore, we use the ray-tracing model to simulate the LGW propagation, and statistically analyze the propagation characteristics of LGW, which are consistent with the observational data. This paper presents the latitudinal distribution and propagation properties of LGW based on statistics for the first time, providing new insights into the LGW generation and evolution in the magnetosphere.
