Looks great Dave!
Nice cell, I have contacted the cell builder if he sells wfc cell parts, but no response yet.
I don't have a lathe to replicate the tube, are the specs exact like SM 3 inch tube-set?

I also had this waveform on a HV cap 1nf, two channel probe hooked up pos,neg.

I still think it is the isolating delrin material what increases the polarization effect.

Thanks webmug,

It turns out I was wrong about my waveform. I took the video down. I'm still getting the same results as my last video. But I can get about 100 volts higher on the new cell which puts me around 500.
Thats a nice waveform you have, I can't seem to get it right. The only time I see it is if the cell is not connected or one of my scope leads is before the choke.
I don't know where to go from here

Question:
are the WFC cells specs you have exact like SM 3 inch tube-set, Delrin or Plastic?

Good to read your new cell has higher voltages! Using and keeping the specs SM has given us.
Do you also have the amplitude "overlap" voltages 180 out of phase? Please test the offset in the primary pulse signal on the core to see if the voltages POS and NEG offset shift up and down. The core magnetic field should be maintained.
Personally I have not tested this, if I have a SM specs cell and VIC I would give it a try!

"...(B) subjecting the capacitor to a pulsating, unipolar electric voltage field in which the polarity does not pass beyond an arbitrary ground..." seen at the POS and NEG.

The tubes are machined to Stan's specs. The plastic is not delrin but is very similar. I can't remember the name.
My signals are not 180 degrees out of phase, That was the mistake I made in the video. I've tryed everything but I can't get them 180 degrees out of phase when I have the cell hooked up. I can get the correct waveform when the cell has no water in it. I'm starting to think that something is missing to make our water capacitor complete.
Anyway, your saying dc offset input is important the keep the cores field from collapsing? I will test for this once I'm using the correct pulsing circuit.

When Stan talks about this unipolar pulse that should not pass ground state do you thing he was talking about both signals from L1 and L2? I'm inclined to believe that only the signal from L1 is unipolar because of the fact that there is only one diode. So far I don't see any rectification from it at all, at least not when I have the cell hooked up.

ps, sorry for my slow response time.

Dave,

Try adding a ground wire from the wall socket or a water pipe running to the negative plate and operate as usual.  An oscope shot of the positive tube will now show only positive pulses.

I've been attempting to make sense of the negative tube to earth ground conection via meyer's electron inhibitor resistor sandwich device. 

For example, I'm up to over 38 mega ohms resistance before I can get a nixie light to dim when connected in series between earth ground and the negative tube in a three inch cell.  This is while running 50v at 100ma at 10khz...

much to learn here, but I like your waveform discussion direction, so thanks

when the L2 coil is 180* out of phase it will cause the core to be constantly magnetized. The 5 -VIC transformer can be looked at as a CVT, Constant Voltage Transformer ;)

One other think I want to mention is that there will be a magnetic field running perpendicular to the coils magnetic field and this will cut out EMF ;)

Interesting, do you mean: Ferroresonance ?

Ferroresonant Transformers

Ferroresonant transformers are a special type of laminated transformer which provides a regulated output.
These are sometimes known simply as "ferros", or "CVTs" (constant voltage transformers).
Using a special magnetic structure and a capacitor, ferroresonant transformers can supply a well regulated output voltage
which remains constant despite changes in input voltage and load. In some specialized applications, these devices can be
designed to supply a constant current output, rather than constant voltage. Current limiting is an inherent benefit of ferroresonant  transformers.
If an overload, or even a short circuit is applied, secondary current is limited to a safe level and primary
current is actually lower than at normal full load. Another inherent benefit is that the ferro serves as a low-pass filter, supplying
to load with power, but effectively removing transient and surge voltages. Energy stored in the transformer structure even
allows the output to "ride through" brief input power interruptions.
