Embodiment Construction

[0023] The multi-directional detection device for space energy particles regulated by grids of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] figure 1 It is a structural cross-sectional view of a multi-directional detection device according to an embodiment of the present invention. Such as figure 1 As shown, the multi-directional detection device includes a collimator 1, a modulation coding grid 2, a semiconductor sensor 3 and a casing 4, where the function of the collimator 1 is to limit stray space energy particles within the detection range; The modulation coding grid 2 is used to modulate the space energy particles in different directions into the semiconductor sensor 3, and the space energy particles will lose energy after entering the semiconductor sensor 3, so they will excite electrical signal pulses on the electrodes on both sides of the sensor. The properly processed signal can give t...

Abstract

The invention discloses a multi-direction space energy particle detection device by using grid regulation, which comprises a collimator, a modulated coded grid, a semiconductor sensor, an electronics section and a housing, wherein the collimator is used for limiting the space detection range of the energy particles; the modulated coded grid is used for limiting the flux of particles in different directions; the semiconductor sensor is used for detecting the energy of the energy particles; the semiconductor sensor is a pixel-type solid sensor, and when space particles enter the semiconductor sensor, due to lost energy, electrical signal pulses are excited at electrodes at two sides; and the electronics section is used for processing electrical signals provided by the semiconductor sensor to provide the particle kinds and the energy for reflecting the space particle energy.

Description

technical field [0001] The invention relates to the technical field of space detection, in particular to a detection device for space energy particles. Background technique [0002] Space-energy particles (including electrons, protons, and other ions) with energies ranging from 1 keV to several MeV have attracted widespread interest since humans discovered the Earth's radiation belts after the first launch of a satellite. Energy particles exist in various regions of the earth's magnetosphere and its boundary layer, and are an important cause of many space physical phenomena such as auroras, magnetic storms, and high-energy electron storms in the magnetosphere. important medium. The acceleration mechanism and origin of energy particles in the magnetosphere are the two most basic problems to be solved in the study of energy particles. The throwing angle distribution of energy particles relative to the Earth's magnetic field lines is closely related to these issues, and is an...
