Richard,
There is an UNTESTED theory that a break rate of 1800 or higher may
be fast enough to prevent de-ionization of the output spark between
breaks and allow the sparks to grow longer, but this design will tend
to draw a lot of power and will probably not work well with neon
transformers.
Typical non-synchronous rotaries tend to destroy neon transformers,
but some people use them. You can use the traditional methods of
safety gaps, chokes, and series resistors to try to protect the neon
transformers. But I don't recommend using a non-sync gap in a neon
system.
Synchronous rotaries are another story -- they work excellently in
neon systems, but they are more work to build. Since multiple static
gaps can work fine up to 4kW or higher, it is probably easiest to use
this type of gap (multiple static gap).

I did not see this effect when I operated my magnifier. A magnifier will not
create any effects that a normal Tesla coil will not produce.
