I agree, Ed, the primary hi frequency energy, I believe comes from the spark
and discharge of the space charge.  Current in the primary loop is a damped
sinewave at coil resonance and has fourier harmonics of resonance.  Energy
from the space charge (that has no current limit and will look like a delta
function) has a fourier spectrum that is spread out over a wide range of
frequencies and will not be coherient.
