Did Don Smith used Avalanche diodes?
In some his builds he maybe used avalanche diodes instead of spark gaps - for timing or for sending pulses.
In the opposite direction as normal diode (using reverse function of diode)

Specifications of avalanche diodes. Reverese voltage of some of them is over 1000 V.
