All,
I just cobbled up my table top maggey driver to monkey around with some
ideas which may make maggey 13. I am labeling this table model maggey
12.
I am using a Hydrogen thyratron 3C35 for the switch. I am pulsing it at
a
1khz rate and its uses about 80-100 watts from the DC supply in this
mode.
I have the driver just running as a simple coil here now and I get about
a
4" spark when tuned to resonance (500khz) and approached with a grounded
rod. It is bright and noisey (k=.55). I am worried that it is still
too
high impedance a driver due to the high Q developed by an otherwise low
Q
circuit! The darned tube actually supplies current to the primary tank
for
1.6 usec (far too short-I think). The coil, due to a large 12"X4"
toroid,
doesn't break out and a stub antenna 10 feet away collects the RF soup
into
an Oscope. I count 50+ rings in the beautifully decremented envelope.
A
huge Q for this coupling! (by normal cogitatin'). I just have to work
on
the phased back to back idea.
A normal neon 60 ma 6KV AC tranny with a rotary gives about an 8" spark
at
160 watts.
The coil is a 10.5 diameter by 6" tall form wound with 20 ga. wire. the
primary is RG 214 of 5 turns. Cap is ~ .008ufd and the tap is at about
18-20uh.
"Sqwat and Hot".
I'll keep you folks up on this one.
