TC components placement
GODSFUSION, Thu Jun 15 2006, 03:11PMWhy is all the componnets of the majority of the designs ive seen have everything under the coils? Couldent I enclose the PS, gap an MMC ETC around the primary? Or it all about asthetics?

It reduce the risk of getting components hit by the sparks.

so I could just enclose my components in a lexan case ontop of the primary round the secondary. being enclosed i wouldent worry bout sparks.

No. Lexan isn't going to stop an arc from hitting your equipment.
Keep the components away from the primary, and especially away from the above portion on the primary.

You don't want to put it above or around the the secondary because if the sparks are longer than the secondary, that is most likely where they will strike, with the possibility of damaging things.

Something I found most interesting was Derek Woodroffe and Jim Mitchell's friendly mini SSTC competition where they often put the electronics inside the secondary:

These SSTCs have breakouts maybe only 1/3 the length of the secondary, max, but were still very fascinating =)

Sounds like you havent actually played with any TCs yet? The sparks can capacitively couple right through thick plastic. Remember, this is very high voltage RF. Capacitors act like a low impedance to AC, so the sparks will travel right through (although at reduced intensity). The best way to keep the sparks where you want them is field control. This is something that you sort of get a "feel" for. Basically, keep conductors rounded, and use toroids/spheres where you want to suppress the breakdown of air.

No not quite ive made a twin mot with the voltage doubler n' such, it wasent too impressive. i dont have a lot of experice in "capacitively couple right through thick plastic" types of cases so I wouldent of known.

A twin MOT Tesla should be plenty impressive- It must have either not been tuned correctly or wires were to long, or caps weren't good or something to that effect. If you still have that design, I say post some details, and maybe someone can help firgure out a couple bugs.

This is what I got out of one MOT:
so two ought to be scary indeed
From these pictures, you might also be able to imagine why we like to hide all the components as low down as possible. One of my good pulse capacitors got struck by a streamer in the second picture.
