The Ion Induced Pinch and the Enhancement of Ion Current by Pinched Electron Flow in Relativistic Diodes.

摘要

A new model for time dependent and steady state ion and electron flow in large aspect ratio diodes is constructed. The electron trajectories are computed using self consistent fields calculated during the initial ion motion. The dynamic formation of a tightly pinched electron flow is qualitatively explained. Very large ion currents, nearly equal to the electron current, are predicted for flat solid cathodes, when steady state flow is achieved.
