电子在水中产生Cherenkov辐射的Geant4模拟

Abstract

Abstract:

The angular distribution and spectrum of Cherenkov photons generated by electrons in water were simulated by means of Geant4. And the energies of the electrons were 05,10,15,20,25 MeV. Then the effect of the secondary electrons on the Cherenkov photons was discussed. Besides, the absorption of Cherenkov photons in water was discussed. It was found that the Cherenkov angular increased with the increase of the energy of
incident electrons. And the absorption of ultraviolet band was obvious in the propagation process of Cherenkov photons in water.

Key words: Geant4 simulation, Cherenkov radiation, electron, spectrum, angular distribution
