Simulation device for electron-excited atmospheric radiation

Abstract

Disclosed is a simulation device for electron-excited atmospheric radiation. An electron gun cavity is connected with a front end of a gas cavity. An electron gun is used for emitting electrons and injecting the electrons into the gas cavity. The electrons collide with gas molecules in the gas cavity to ionize and excite the gas molecules. According to the miniaturized simulation device for electron-excited atmospheric radiation, the device can realize an ionization excitation experiment of high-energy electrons on neutral gas and generate a series of optical radiation phenomena in special scenes. In addition, with the aid of optical observation equipment, optical radiation signals of ionized neutral gas can be obtained, so that radiation laws under different incident electron energies, different radiation intensities and different atmospheric components can be further obtained.
