W/E it is with the chokes we wont see anything unless we find a proper oscillator circuit .

There is an inductance coupling between each resonant cavity of the resonant coils (14) of this coil assy that require them to be seperate sections.



inductance coupling of what?....the primary and secondary magnetic field?......if i am making mine on two seperate cores what would be the point for individual segments.....i remember in his patent where he talks about vic size and shape he doesn't mention anything about segments jsut 100 wraps of bifilar 24 gauge wire about an inductor core.....and that if you increase length you increase voltage output........i really hope this is right god forbid i do short this out becuase of the damn sections.......but i don't think it will happen....hope*

i think it might have to do with the inductance from the inner and outer bobbin to the bifilar chokes bobbin...maybe it spreads the magnetic field out more evenly....
absolutely!
Try think of a better way to wind the bifilar so that it captures all the primary induction lines, wound uni-directional (so formed kV HV doesnt couple with LV, Cd is small, but many of em), KISS.

the sections could also be a part of the KISS approach, equal sections, easily expendable.
the sections remind me of  pseudo pancake coils....  in parallel.

"There is an inductance coupling between each resonant cavity of the resonant coils (14) of this coil assy that require them to be seperate sections."

as seen in fig 6-1 (511a - n) and (512a - n)

I believe the seperate segments are required to allow the coil to charge.  Using the inductance between segments to hold and increase the charge of the gated - pulsed - DC current.

thank you alan and john....i think i like alan's explanation.......so just to be safe and follow stan.......i will create a bobbin for it with some nylon spacers.....

chokes,

1- The current that an inductor can handle depends on the size of the wire. The inductance
does not; it is a function of the number of turns in the coil, the diameter of the
coil, and the overall shape of the coil.

2- In general, inductance of a coil is directly proportional to the number of turns of
wire. Inductance is also directly proportional to the diameter of the coil. The length of
a coil, given a certain number of turns and a certain diameter, has an effect also: the
longer the coil, the less the inductance

3-Very small coils, with few turns of wire, produce small inductances, in which the
current changes quickly and the voltages are small. Huge coils with ferromagnetic
cores, and having many turns of wire, have large inductances, in which the current
changes slowly and the voltages are large

4- As long as the magnetic fields around inductors do not interact, inductances in series
add like resistances in series. The total value is the sum of the individual values. It’s important
to be sure that you are using the same size units for all the inductors when you
add their values.

straight from the books fellas,

-all in all we know that current is determined by size of wire used.
-inductance is determined by geometrical demensions of coil  and has direct relationship to number of winds.
-the longer geometrical coil the less inductance.. thats why 6-1 magnifies in individual cavities it is considered a 16th of an inch inductor. and its like having 14 seperate chokes in series. its also why the choke in his water polarization unit is small.
-Huge coils with ferromagnetic cores, having many turns of wire, have large inductances, in which the current changes slowly and the voltages are large

note of number 4- As long as the magnetic fields around inductors do not interact, inductances in series
add like resistances in series..
they are definatly interacting which would take away resistance in 6-1. this i beleave is why the all in one unit requires resistive wire.  then again depending on how the choke wire is wired you can have 2 seperate wires (Bifiliar) flowing the same way?

this is not my thoughts on how i think the chokes work.. it is textbook material. hope this helps

*********choke core materials*******

Powdered-iron cores are common at radio frequencies. Ferrite has a higher permeability
than powdered iron, causing a greater concentration of magnetic flux lines
within the coil. Ferrite is used at lower radio frequencies and at audio frequencies, as
well as at medium and high radio frequencies.
The main trouble with ferromagnetic cores is that, if the coil carries more than a
certain amount of current, the core will saturate. This means that the ferromagnetic
material is holding as much flux as it possibly can. Any further increase in coil current
will not produce a corresponding increase in the magnetic flux in the core. The result is
that the inductance changes, decreasing with coil currents that are more than the critical
value.

********Permeability tuning************
Solenoidal, or cylindrical, coils can be made to have variable inductance by sliding ferromagnetic
cores in and out of them. This is a common practice in radio communications.
The frequency of a radio circuit can be adjusted in this way, as you’ll learn later in
this book.
Because moving the core in and out changes the effective permeability within a coil
of wire, this method of tuning is called permeability tuning. The in/out motion can be
precisely controlled by attaching the core to a screw shaft, and anchoring a nut at one
end of the coil (Fig. 10-7). As the screw shaft is rotated clockwise, the core enters the
coil, so that the inductance increases. As the screw shaft is rotated counterclockwise,
the core moves out of the coil and the inductance decreases.
