I'm pretty sure deuterium (D) is even rarer than helium (He). So while you can produce He from a D-D reaction, it would be the analogue equivalent of making lead from gold.

U-235 can do it automatically by reaching a critical mass. U238 is another story however as that would require an entire reactor.

The output is way too small and short lived. You'd be better off with a regular neutron generator and frankly, there are already plans for just such reactors.

Not U235. Your thinking Pu239 reaction.

Yes

Great question ... government secret I’m assuming

Probably. And NO, you can't have one.

2:47 ok it's limited :)

It's a short duration 600 volt pulse that boils off deuterium from the "heater" and accelerates them to a target that's variously been described at titanium tritride or titanium deuteride. Personally, I'd have went with a different metal on one part and bumped the acceleration voltage up a couple of orders of magnitude or so and gotten a wee bit higher neutron flux, although at differing thermal levels.

@@spvillano The heater is powered with low voltage, while the Anode and Cathode have a high voltage across them.

If you had 1 mole of deuterium, and released 1 neutron per second, how long would that last?

Don't tell me to flux off please.

Good luck. You would have to be licensed

Yes, but small amount....

You're better of using Am-241

Couple of giga amps, sorted.

NO. You can NOT have one..

I imagine because it is only producing hundreds of neutrons, it will probably consume the deuterium very, very slowly

It’s a $2,000 component. You throw it away and replace it, that’s the whole point.

Yep. Disposable and "cheap".

From a macroscopic point of view, in all directions, but in any given case, in the opposite direction of the neutron (and much slower) owing to conservation of momentum.

Couldn't you redirect them w beryllium lensing

@@Blackrain4xmas possibly, but why? The neutron count is brief and low, the helium output would be tiny as well.

deuterium burnup and fusion products should be negligible given the low amount of neutrons these produce

I think you meant tritium, or h3, which is radioactive. Deuterium is a stable isotope of hydrogen.

@@bulldogcowwy3959 yep i was wrong. dueterium is in fact a stable isotope of hydrogen :3

@@stellabckw2033 you get a tritium and a neutron when you smack the two tritiums together so you still end up with it but i guess it decays to deuterium and becomes stable again

when two deuteriums hit each other you end up with helium-3 apparently so it's still stable i was wrong about it creating a tritium and and a neutron

Quarks are the heavyweights in a nuclear strong-force reaction, and really require accelerators half the size of Rhode Island to make them.

you have no idea what you're talking about, quarks are confined to hadrons or mesons, they cannot be isolated.

@@sidewaysfcs0718 not really, just hard to isolate a quark-gluon plasma and keep it that hot. Some thermodynamics law or something about no such thing as a free lunch. ;)

@@sidewaysfcs0718 yep. I'm not an expert but that's what Brian Greene has said in his books - that is quarks and gluons are trapped in their respective hadrons.

@@spvillano If you pull the quarks gluon - quark pairs apart that energy will be used to generate a quark for each of those "isolated" quarks. It's kind of like pulling a rubber band apart.

No

Detecting fissile material (like Pu pits) maybe. But you sure as hell aren't going to initiate a fission bomb with 10^3 neutrons/sec.

It probably does not produce enough neutrons to serve as an initiator in a fission bomb.

@@donaldasayers Could be scaled?

@@willett786 True to a degree - but the people who have access to the rest of the components of the bomb, already have access to initiators that would cost far less than (massively) scaling up things like this I think.

I think He means breeding plutonium. There's still much easier ways to do that though.

I worked in electronics for many years, never saw a metal film resistor that didn't have a connection between the connectors. More like an almost spark gap, save that this appears to be more like an electron gun modified to fire deuterium.

@@spvillano It is...

Well it emitted some stuff and then it went off the screen before you had time to complain about it. Sorry sweaty!!!!

It was accurate, the neutrons just came off of a busy holiday weekend and were dragging a little. ;)

No. It's a completely real device, and it works

It's a collision followed by fusion....you're fusing two nuclei together and expelling a neutron, this isn't a runaway reaction since it's not triggered thermally, it's a non-equillibrium process.

This does cause fusion, and yes you get a prompt gamma with each reaction. A few hundred of those per second would take days of continuous exposure to be lethal. Nuclear reactions do not depend on quantity, it's a fundamental process.

@@sidewaysfcs0718 which every current artificial fusion reaction is. We can't yet sustain such a reaction, let alone manage to make it runaway.

hush

You could use it to fire neutrons at a thorium reactor.

Thing is, if they can start to fabricate these in bulk and miniaturise further, - possibly even encapsulating the entire product, it may be possible to end up with a layered / stacked device so that devices with 10X 100X output would be attainable. You then just use as many modules as required. I guess though at some point, a more conventional tube design gives a better neutron / cost yield. As you say interesting - and perhaps a technology that will yield more powerful devices at lower cost in the future. In the meantime, recovered radium (reclaimed and part purified from old watch and clock hands) and beryllium powder still gets the job done for tiny output requirements for amateur experimenters like myself.

Well, there are people (Phoenix LLC in Monona, WI) making glorified Farnorsworth Fusors that do compete with AmBe and Cf sources.

That's like saying that a single transistor is useless because it won't process your word documents... These things are meant to be used in giant arrays.

@@silverfox2358 too low a number of neutrons and let's not even go into their energy level. Better served with a traditional neutron source.
