Re: TCBOR Magnifier 11-E Specs

Ed,
Primary Qs have not even been a remote thought here and therefore I have no
instrumented, experimental data. I believe that beyond reducing the RF, AC
current losses within the conductor, one primary is little better than
another. The geometry is a factor based on the degree of coupling desired
and specific application. Remeber, the primary is just a way of dumping
magnetic energy into the secondary and a lot of ringing within the primary
of a magnifier is a definite no-no! This is because the pri/sec of a
magnifier is grossly over coupled (magnifier) and we must open circuit the
primary immediately after the first peak pulse of current from the
capacitor's discharge. Therefore, the primary is out of circuit most of the
time. We want one single pulse only. Tesla spoke well when he suggested
large flat banding for primaries. The peak currents in this coils can rise
to 1000 amps easily in larger systems. Our current magnifier has a measured
peak current when running, full tilt, of about 655 amps.

I agree. My first goal is not always trying to optimize sparks. I
want to understand whats going on too.
Here's where I'm coming from though - Malcolm has done some measurements
which seem to show that primary circuits have Q's of about 10 no matter
what L,C combination one uses. Well this seems to imply the spark gap
as the culprit then for the major energy loss in the primary circuit. It
also, not suprisinly, behaves in a non-linear way to the current passing
through it. Morecroft (I think) says that spark gap circuits tend to decay
linearly, rather than exponentially as in pure resistive circuits. Have
you( or others) seen this?
