Completed solution for space-charge-limited currents in
initially monoenergetic electron vacuum diodes

Y. Feng (UCB-NE)

The solution for space-charge-limited (SCL) currents in initially
monoenergetic electron vacuum diodes is extended to relativistic
regime. There are two types of solution found where type I corresponds
to zero steady state surface electric field and type II corresponds to
a finite steady state surface electric field. Our solution has been
compared to the classic space-charge-limited currents with initial
energy and relativistic space-charge limited currents without initial
energy.
