After the conference earlier this year related to Gamma ray and X-ray detection from high lightning strikes on some science birds, some people hit the field with sensitive equipment to see if these could be picked up at large Tesla coils and Marx generators.
One of the Tesla sites was Boston Science Museum and other sites, NO bad stuff was found.
The Marx generators on the other hand had plenty to show in these energy regions.

Thinking here that high-intensity sparks produce a very loud sound. The sound means that a large amount of air is moved away from the spark channel. Maybe for some time interval a high enough vacuum is formed at the spark channel, and electrons are accelerated to high enough speeds there by the electric field.

Time scales are wrong. The expansion of the gas in the channel would be much slower than the time course of the pulse (microseconds). More likely some part of the channel might be hot enough to emit soft xrays from the far out tail of the blackbody curve.



When they shock against the air around
the channel X-rays may be emitted.
