This is what happens when you pulse a coaxial cable.

Thanks 27Bubba, for opening this thread, i put here below the important posts i made in the other thread:


============================================================================================
Thanks for the encouragement T, but as i already was experimenting with coax cable coils, i already was intriged by this selfrunner.

I have a hard time understanding the Russian drawings/text etc, but slowly more info is coming in English.

My first attention is to the main coil, and i came up with the following info (all CW):

L1 = 820t 0.25mm on 4.6cm former (white/orange leads)
L2 = 315t 0.65mm on top of L1     (magnet wire leads to caps)
L3 =  41t 5.9m Coax cable        (probably NOT RG58 as to my knowledge RG58 is always black coated)
L4 =  72t                        (combination of brown and blue cable) not sure what thickness.


I started building my coil and use:

cardboard former 5cm:
L1 690t 0.4mm  3.3mH / 14.5 ohm
L2 380t 0.6mm  1.5mH /  0.5 ohm
L3  41t (6m) 75 ohm coax shorted at 1 end
L4  i will use 70t of some kind of wire i have laying around.

Questions for me presently are:

How to create this 1-5ns pulse (my FG generates a 80ns pulse at best)
What is the amplitude of this nano pulse (5v?, 500v?, 5Kv?)
What is the frequency/amplitude and pulse shape on the L1 coil (match the resonance frequency of L2 tank coil?)?

Video to be seen here:  http://www.youtube.com/watch?v=MQUciCy9p3A&feature=youtu.be
I will try to get more to the point in the video's, thus shorther, in the follow ups if any.

Next will be to make some measurements on the coil when pulsed.

Thanks a lot for this info T-1000, so it means that even the creator of this device is not sure about the used wires of his coil.

Well, i finished my main coil and did some measurements/testing, including HV puls testing on the coax.
Here is the data on MY coil:

Cardboard former 5cm od

L1 690t, 0.4mm, 3.3mH, 14.5 Ohm, selfresonant (so no cap) on 2.4Mhz   (magnet wire)
L2 380t, 0.6mm, 1.5mH,  0.5 Ohm, resonance with 600nF cap on 5.071Khz (magnet wire)
L3  41t, 75 Ohm coax (tv) foam pe isolation, velocity 78%, 1 end shorted
L4  64t, stranded HV, 72uH, 0.8 Ohm, selfresonant (so no cap) on 4.8Mhz (Belden 24Kv HV cable)

Video of the testing here:  http://www.youtube.com/watch?v=utkIltw6WrU&feature=youtu.be

Great questions from d3x0r: "How about that toroid? is that a standard component from something?"

I also am looking for data on that toroid, like diameter, type/make, number of windings (4?), number of turns, wire used etc.

Anyway, parts are on order for the Main generator and for the pulser, it will take a while for them to arrive.

Regards Itsu

==============================================================================================

d3x0r,

from one of the diagramms i have printed out (i don't find it anymore on the forums, as it seems that data/diagramms are coming and going),  i have got this info:

Ferrite Ring probably 4cm od

Windings 1 and 2 are  3 turns 1.5mm
Windings 3 and 4 are 70 turns 0.6mm

Perhaps this can be confirmed by others.


Regards Itsu

================================================================================================

Yes d3x0r, you are right,  forget about the mentioned toroid.  It would be more like 4cm od, but the windings/turns could be accurate.

I have editted the original post to read toroid probably 4cm od.

By the way, i found the missing diagram, its on this webside:
http://realstrannik.ru/media/kunena/attachments/1226/dally1.GIF

The Russian text in the middle is to my understanding the data on the TP

Itsu

=================================================================================================

Hoppy,

the line in the middle of the drawing (ТрансÑ,,ормаÑ,ор на Ñ,,ерриÑ,е оÑ, Ð'п ATX)  translate via google into: Ferrite transformer from the PSU ATX

So i guess its a mistake on the transformer symbol and it really is a ferrite based transformer.

All,

Concerning the main generator (4.6Khz) toroid, i found this diagram which contains some data on it:

http://realstrannik.ru/media/kunena/attachments/1226/dally1.GIF

meaning:

Ferrite Ring probably 4cm od

Windings 1 and 2 are  3 turns 1.5mm
Windings 3 and 4 are 70 turns 0.6mm

But looking at the original pictures like Hoppy already mentioned, this does looks more like a commercial
toroid with much more wire on it.

While waiting on my parts to arrive, i was experimenting with a toroid i had laying around, see picture
(2 turns primary / 40 turns secondary), but was blowing up my MOSFET driver chips 4420 (MOSFETS IRF630) :-)

Questions:

# these 3 (or 2 turn) primary, act like a short to the MOSFET's, right?  Should there not be much more turns?
# these primaries (1a and 1b) should be CW and CCW, to work in this push/pull configuration, right?
# the secondaries (ii and iii) can be either CW or CCW, right?

Thanks,  Regards Itsu

Thanks a lot for this info T-1000, so it means that even the creator of this device is not sure about the used wires of his coil.

Appears so.
The dimensions of the coax coil and its operating frequency should be very critical if it is important to achieve standing wave superposition.

The following deserves a 3D animation of a standing wave in a coaxial cable but since I cannot find one at the moment, I'll have to use too many words. Sorry about that.

The standing wave in a transmission line (e.g. a coax) is created by the sum of two waves traveling in opposite directions - the forward (incident) wave created by the signal generator and the backward (reflected) wave created by a shorted (or open) end of the transmission line.
The two waves interfere constructively and destructively (add up and subtract) forming stationary nodes and antinodes. The resulting standing wave has twice the amplitude of the incident and reflected waves. This can be seen here.

In any EM wave, the electric (E) vector and magnetic (B) vector is always mutually perpendicular, however there is a difference in the temporal distribution of the E and B vectors between a standing wave and traveling wave. Namely:
a) In a traveling wave the E vector is at the maximum when the B vector is at the maximum (0 degree phase difference). See here.
b) In a standing wave the E vector is at the maximum when the B vector is at the minimum (90 degree phase difference). See the attached picture (unfortunately not a 3D animation)

In the second case (the b case) one might notice that the E and B fields are separated in time (and space).
When a standing wave is induced into a shorted coaxial cable, it is possible to align the nodes and antinodes of the standing wave by folding the cable in such a way that theese nodes are next to each other, e.g. by folding the cable into a serpentine or a helix.  This special arrangement will lead to the superposition of the perpendicular E and B vectors of each fold or turn.

For this to happen in a coil (helix) the distance between the nodes of the standing wave has to be equal to the circumference of each helical turn of the coaxial cable.

@Itsu
Can you visualize this without the 3D animation?

Since you are an experimenter, I suggest that you visualize the standing wave in a straight shorted coax (fed by your signal generator) just like this guy here.

Verpies,

@Itsu
Can you visualize this without the 3D animation?

I can create this picture in my mind, yes.
As an (inactive) HAM radio amateur i struggled with standing waves on coax many times (to get them go away :-) )

For this to happen the distance between the nodes of the standing wave has to be equal to the circumference of each helical turn of the coaxial cable.

This means that for my shorted 41 turns coax coil of 6 meters length i have to have a node every 14.6cm (6/41).
Having 2 nodes/wavelength, this means a wavelength of 29.2cm = 1GHz.   Correct?

By the way,  great links again, i will do some time domain tests on my coax.

Regards Itsu.
