Screw winding idea

[aleks]

Previous picture zoomed in.

I'm not an EE myself, but I'm talking to an EE I know and we'll probably try to pulse this scheme in different variants. I plan to use frequency-adjustable sawtooth waves (10MHz is max) and DC voltage in various combinations (@ 12V peak).

Since a single screw has two "halves" (two coils), variants I want to try are:
1) sawtooth in both halves, in the same current direction;
2) sawtooth in both halves, in opposite current direction (I have my hopes on this one as this should create "kicks" twice as powerful).
3) sawtooth in half 1, DC in half 2.

Beside that coils can be run parallel or serial, so this adds additional variants. If possible I'll try inverse sawtooth as well. Spark gap is also possible, but is not as interesting to me.
