Re: New to the group / ion cloud
Do these sparks result from the ions colliding thus forming the continuous
conductive path that is the arc?
Is a brush discharge thus in reality the same ions only in a collisionless
state (hence no arc)?
In "Electricity at High Pressures and Frequencies" by Henry L. Transtrom, a
recipe for the brush discharge is suggested on pages 207 - 208.
'By using only the two top turns of the primary coil, and having
considerable inductance in the primary circuit of the step-up transformer,
the whole top of the high frequency secondary is covered with a beautiful
spray so fine and dense that it looks like the fine spray of a fountain,
only colored a bluish violet.'
I am having difficulty visualizing what the above adjustments mean
electrically, and why does this cause a brush discharge? Can anyone shed
some light on this puzzle?
