Preliminary Study for Improving Electron Emission Threshold of Metallic Electrodes Treated by Intense Pulsed Ion Beam

There exist lots of impurities and micro-protrusions on the surface of metallic electrode, which lower the electron emission threshold. Since intense pulsed ion beam (IPIB) irradiation can melt and vaporize metal material, it is expected to increase the electron emission threshold by removing the im...
