This simulation shows primary and secondary interaction after a single firing of the spark gap.
The effects of different coupling coefficients and spark gap quench times can be studied by altering the appropriate parameters and re-running the simulation.  Coupling is initially 0.1 and the quench occurs at the 4th primary notch.  Primary and secondary voltage waveforms are displayed initially.
