Automatic High Precision Energy Acquisition System Based on Electrostatic Analyzer

A fully automatic high precision energy acquisition system based on electrostatic analyzer which was successfully used in the experimental study between micro clusters and graphene was realized. Based on this system, the interaction process of 1.8 MeV H⁺₂ micro-clusters with 4 layers of graphene films was studied, and the energy spectrum of the proton after the Coulomb explosions as well as the spectrum of the transmitted H⁺₂ was measured, which greatly improved the speed of data acquisition and reduced the experimental error. The measurement results show that the energy resolution of the system is about 0.6 keV for the 1.8 MeV H⁺₂, which is of great significance for the future high precision energy spectrum measurements.
