Single circuits generate nuclear reactions

Pulse supply at 24V. Square wave (under 10ns rise and fall times) from 1KHz - 4 MHz.

Well, it should not work. I've spoken this idea a lot of times on many threads here on OU. You have to use discharges or low duty-cycle square wave. Pure square wave won't work since it is symmetrical. Not to say you are likely not producing enough current with square wave generator. 24V at how much amperes? Avalanche MOSFET pulses should be used, or capacitor discharges. Anything "interesting" was produced with these two only (plus spark gap). I have not seen any good reports with square wave gens: their transients are counter-acting each other thus nullifying overunity energy. Well, low duty-cycle square wave may not work as well: it is still a pulse with symmetrical transients.

sorry - I assumed a lot in my post ...

15% duty cycle pulses and pulse duty cycles down to 1% also tested. No difference. All pulses are extreemly low impedance - ceramic bypass caps are right on the main power supply. Even at low duty cycle the large diameter graphite gets quite warm. All pulses are biased 0 - +ve -- not symetrical around ground.

The switcher is set up to handle 550V at 35A pulses - ceramic caps on the supply are backed up with pulse cap (2KV at 100's amp continuous use - KA's for short bursts). My HV supply is under reconstruction at present which is why the HV pulse tests have not been done -- plus it is prudent to do the 24V tests first to asses the ammount of heating and any other problems that might arise when pulsing with a lot of power.

I've added a comment to my post above - varying duty cycle may not work as well. It still has symmetrical transients. Transients should be non-symmetrical like discharges (spark gap) or saw-tooth waves. I'm not talking about DC symmetry. I'm talking about transient (delta) symmetry. With square wave you have +2.4V/nanosecond transient then -2.4V/ns transient, etc. With discharges you have +2.4V/ns transient and then a -0.01V/ns transient.

Low-passed square wave won't work for the same reason: even though it does look like a discharge, its every other high transient negates previous high transient. It may work, but I'm not sure.

It even did it when the end of the fricking diode lead was just sticking up in the air, not touching anything.

when I say there was NO voltage across the diode, there was NO voltage across the diode. I checked and re-checked it three times since I posted the photo originally.

No continuity in the circuit until the switch is closed, resistance of circuit is 980 or so ohms. 989. fluctuates a little bit due to el-crapo 3 dollar meter.

NO voltage across diode.

Well that's a bit weird, I would really have expected some voltage... 

Diode also checks out as good with built in diode tester.

No clue what's going on.

Also, not sure how 9mW would warm my hand unless it was beta that was being focused by C shaped aluminum housing.

Yes, that's exactly what I was thinking... So there does seem to be quite a bit of beta coming off it, but it doesn't show up
on the diode as voltage?
Well knock me down and call me timber... What the flippin flip is going on there?

Checked continuity between all parts of circuit (resistor, diode (when free standing), circuit board contacts, power, ground, and switch terminals) and the aluminum shield.

NO continuity. Shield is floating electrically, and sits only on insulated PC board. on other side of board is a patch of epoxy that was holding on battery clip from a previous project. recycled PC board. no shorts anywhere on board, since I used a previously unused section of the PC board. Its a DIP breakout board from radio shack.

hmm... what if you hook the aluminium collector to the diode to a cap, and the other cap terminal to a diode to the carbon again? If you're not getting any
volts from the aluminium collector now, you're probably not going to get them then either... idk...

Totally weird crap, and I'm going to sleep.

Lol well you've given it a good shot.

just some tape, magnets on the resistor, and a diode, and a piece of aluminum foil near the diode. No clue. Try it. Burn your finger.

Join the club!

Rofl Burn your finger, join the club! lolz

Nice tests R, you are the McGuiver of EE;  sorry to those who couldn't get the effect yet. Remember use a nice strong magnet bias and try a higher ampere / higher voltage discharge.  See if you pick up anything on your counter.  Put your counter close, and remember your magnets may be causing the beta to curve into some sort of stream.  . . So check around your device at different angles for the presence of beta.  If you still cannot get an effect, post a photo of your setup and maybe  we can figure out what to modify.

My counter is on the way, my setup will be DC pulsed square wave (at variable frequency 1khz and up) into 12mm long carbon rod at  200-500V+ 0.25A-5A, or else around 48V at 30A. I will try both and measure beta output with the geiger. I can also try single-shot 200-1000V at 10uF as well, but this capacitor has not arrived yet.  I will be using 30+lb  N45 neos to bias the rod both axially and anti-axially depending on the particular experiment. 

I will check all configurations against control for beta electrons.  Supposing I can confirm presence of beta in my replication, I will then attempt collection.  If you are trying replication , please do not claim "it doesn't work" unless you are actually scoping for the beta electrons with a working counter and can't find any.  If you cannot find them with the counter, please post a photograph of your setup.  Thanks!

I saw your idea, I like it, but I am really bad at LC circuits.  Perhaps you should message groundloop and zerotensor, I think they both were discussing using variations of these... sorry at work will try to read it more carefully this afternoon.

@Mark
Can you post a photo?
