Single circuits generate nuclear reactions

[DrStiffler]

@All
Well I will not respond to my own thread while on vacation, but I see something here and just can not keep enjoying the surf and all.

*Runaway is not possible unless the reaction was self sustaining once started. A simple in line fuse and a Zener diode should be the cheapest way to prevent such things.

Regardless, the worst that can happen is you burn up a few parts before it all shuts down. If you try feeding the output back to a power supply and say you use a  chip regulator, it will self destruct.My guess would be a couple of hi power zeners that are a few volts apart and a fuse inline. This will shut it all down.

I have an associate in this field and he is still unclear on configuration (as am I). When this can be cleared up I will commit three Ph.D's and myself to replication, I am planned to return to Texas Thursday and the lab can get ramped up for my return.

Love the concept and hope that (U * t) is being properly applied here.

So far great work and looks like someone will be collecting a few prizes.

Hey Doc

We agree with your analysis.   Runaway is unlikely, could can only occur in direct connected feedback because semiconductor would burn out first.   But if someone uses un-fused direct feedback, we think runaway may be a real and potential hazardous effect. 

We think 'runaway' depends on thermal conductivity and mass of the carbon rod. There is potential for Z-pinch effect within the rod causing exponential increase in current density during the runaway.   This depends on resonant freq of circuit as a whole, but once it occurs reaction can become self sustaining and thermally decompose carbon rod (ala firecracker). This would shut down reaction but would fracture the rod but release and as-yet uncalculated amount of thermal energy (rather like a carbon arc lamp), but with much much higher current densities.  The Z-pinch doesn't increase absolute current, but resulting magnetic field restricts current to much smaller cross sectional area, which could result in extremely fast increase in the rate of reaction in the affected cross-section.

Due to small mass of the rods, physical damage should be rather minimal.  That is, low total energy but higher power. So very fast and powerful but not necessarily high energy.  But this could mean fragments of carbon rod, which may pose a hazard in the unlikely event someone manages to achieve Z-pinch effect combined with this Synergetic/NMR proton-electron phenomenon within the carbon orbitals.

We think this can be prevented by using PWM, or as you mention, always using some sort of fusing when operating in self-powering modes.  We also consider the 'runaway' hazard to be minimal when the circuit is configured properly (aka 'fused').  We look forward to your return and contributions to this research.

Gentleman we have a SEC15-30W ready for testing. The 30W is capable of up to 600V output, yet what would be nice if possible is to specify the pulse in Joule/Sec? The specified 300V and 300amps seems to require a small clarification? Is it possible to state the Joule/Sec required.

We are ready with Beta counters in place, should be an interesting test.

Dr Stiffler  you might as well come home  you'll have more fun in the lab  this is beyond exciting   Chet

Maybe, guess my legs have been cut so short that I have a hard time getting to into anything any more.

It sound like you have seen something of interest? Can you tell us what voltage across what capacity and rep rate is so exciting? I do not want to go through the bottom up as we already have HV generators that can be run PWM with ease, but what is being required in watt/sec? I fully understand this will depend on rod size etc., but a good place to start? The lab can manufacture the drivers in 10 days for mass distribution if this indeed is what it looks like.
