Hey.
While the title promises "low-inductance bla bla bla", I have been a big tease so far!
The high-speed, low-inductance switch is a key part of what I am working on, and all this messy preamble serves to do is give things a context.

Goals for this switch:
1. Fast.  Duh. Arc-switches are the fastest power-switching technology known.
2. Low inductance.  See also Fast Switch.
3. Physically robust.  No weak-tea falling apart nonsense.
4. Cheap.  Like me, no budget, so gotta be home-made.
5. No Inobtanium, Cantfindium or Whatthehellamine.  No fair if my cool design relies on "An Interositer capable of laying a 6 lane concrete highway at 70 miles an hour!"  "This Island Earth", comment made by Scientist while reading Alien Electronics catalog.
6. High repetition rate.  Because repeating faster is better.
7. Small design.  No fun if it is the biggest part, eh?
8. PCB mounted.  As the PCB is the basis of the capacitors, having the switch integrated into the capacitor speeds things up.
9, Enclosed arc-gap.  Arc-gaps are loud [electronically and acoustically] and emit tons of UV radiation.  Enclosing the arc-gap makes for nicer neighbors.
10. Maintenance free.  Like they said just before the Coroners Inquest, Remains to be seen.  See Enclosed Arc gap.

What I am doing with this dream-switch?
TEA laser, because I can.
Water-arc explosions.
Water-arc explosion mediated chemistry/transmutation.
Thin-film explosions.
Bending the rules of time and space.
Making the flying car they have been promising us since the 1950's.
Killing the Standard Model.
Getting humanity off of this rock.

Yeah, time to see my Doctor...
