Observations of Multi-directional Particle Detector from HXMT
Abstract
Hard X-ray Modulation Telescope(HXMT) was Chinese first space astronomy satellite, which launched into 550km with inclination of 43 °on June 2017. The Multi-directional Particle Detector on HXMT was designed to provide measurements of energetic protons and electrons. The detector is an all solid-state system that can make 16-directional flux measurements of electrons with energy ≥200KeV and protons with energy ≥1.5MeV, and can also measure the differential energy spectra of electrons from 0.4_>1.5MeV and protons from 3_300MeV with 7 channels separately from single direction. The detector can characterize particles distribution for detail especially in SAA which is important for low earth orbit missions. Here, we give brief induction of the instrument and show the primary observation results from the Multi-directional Particle Detector and evaluate the effect of anisotropy on flux measurements.
