Preliminary Investigation of Anomalous Relativistic Electron Beam Deposition into a 10 exp 17 to 10 exp 20 cm exp -3 Density Plasma

摘要

Based upon recent theoretical and experimental advances, the potential for using a 10 to 30 MeV electron beam to heat a 10 exp 17 to 10 exp 20 cm exp -3 density plasma has been investigated. Taking into account anode foil scattering, external magnetic field strength, electron-ion collision rate, beam self-magnetic field discontinuity, and plasma temperature, a coupling efficiency of 15 to 50% is achievable for such a plasma. Moreover, the beam generator requirements seem to be within present pulse power technology. (ERA citation 03:041935)
