Single circuits generate nuclear reactions

[Reiyuki]

Maybe I should have been more specific as to my intentions and reasoning for a tesla based VSG.

The main goal by using a high voltage (IE: Tesla) setup was to take advantage of the 'ring down' effect on an LC circuit.
All properly tuned tesla coils do this, and that high-frequency back-forth would give you an effect somewhat like:
Initial pulse, 250amp
negative wave, 230amp
2nd wave, 210amp
next wave, 170amp
next wave 100amp
etc etc

So, if the requirement for the capacitance would hypothetically be much lower, because that resonant ring would turn a single discharge into 3-20 AC pulses.


I can't see it being done in low voltage without some sort of kilohenry inductor or something.

Sorry I've been gone for so long. I have a bunch of blown Mosfets and IGBT's to show for it though = ) No power out yet using low voltage. The high voltage version I was never able to try with an alignment field (other than magnets) though. The current transformer and Geiger both register even with just a simple capacitor discharge with no alignment field. Clearly these devices are being affected by the pulse itself (emi) and reading incorrectly. I believe this also happened with the JLN experiments.

This is all with no tungsten across the gap of course.

I have attempted to repeat Naudin's VSG experiment again, this time with guarateed pure carbon and a 3% thoriated tungsten rod so far without success. I suspected at first that the toroid might be saturating preventing the reported increase in energy in the carbon from appearing, reducing the voltage to the capacitors still showed no sign of the VSG effect. The waveforms, with and without a magnetic field along the carbon, recorded on the Tek storage scope,  are identical not just similar.

The only difference is that I am using a total capacitance of 0.008 F, whilst Naudin's capacitors are somewhat bigger at 0.0094 F. I have also been using lower voltage around 60 volts in these tests, slightly higher than Naudin used in his earlier tests.

Another possibility is that my capacitors are switched by a large stud mounted thyristor which can take several thousand amps, these devices are relatively slow to switch on compared with a MOSFET, but nevertheless I would expect some output difference, with and without the magnetic field, even if less than in Naudin's case.

Regarding the beta radiation, I do not believe there is any. I covered my geiger counter tube and driver circuit in grounded aluminium kitchen foil to reduce EMI and tested it with the 1.2 Mev beta emission from potassium chloride (culinary salt substitute) and it detects beta even through the al foil, so it would surely detect the supposed more energetic radiation from carbon. Also I notice Naudin shows the geiger counter up against the toroid, I do not believe that beta would make it through 1 inch of transformer iron, even if present.

Hi Mike,

I admire your tenacity, I wish the effect had manifested for you. Would it be worth your while eliminating the thyristor switch and making a spark gap that you can slowly close by hand to discharge the cap into the rod, it should give you a faster rise without having to purchase any extra parts?

[mikewatson]

Yucca,
yes a spark gap could work, I am thinking of using a mouse trap with a couple of fat copper contacts possibly amalgamated on the surface with mercury, where the mouse's neck would go. Mechanical switches are electrically noisy, but mercury gets rid of that. Unlike expensive FETs this type of switch is cheap and is also very fast closing, in less than a nanosecond, and pretty well indestructable.

I still believe Naudin's results so somewhere I must have done something stupid.
