Abstract
The relativistic-electron-beam (e-beam) generation initiated by field emiss ion from a graphite-nanofiber cathode is reported. The completion time of t he plasma-sheath formation over the cathode surface is discussed in terms o f observed diode perveances. A short plasma-sheath formation time of 25 ns is obtained at a macroscopic electric field of 85 kV/cm. This type of emitt er can be used for e-beam sources for pumping KrF lasers.
