DIY Nuclear Fusion Reactor - Deuterium Fusor

It is important to note that throughout these experiments, I wore an Arrow Tech W138 X-Ray/Gamma dosimeter. It never showed any radiation dosage above background. I also wear a lead radiology apron for additional radiation shielding as a precaution. For more information on this project, please check out my detailed postings on the fusor.net forum:
fusor.net/board/viewtopic.php...

[@ScienceMarshall]

For all those interested in power generation, please read this pinned comment. The Farnsworth fusor is NOT a power reactor. The actual fusion energy being generated here is MANY orders of magnitude lower than the energy going in. This reactor is only used to demonstrate that nuclear fusion can be achieved on a small scale and as a decent neutron source. So please don’t ask how much power is being generated here or if it can be used to power your home.

Too bad I didn't see this video earlier, it would have saved me time! I'll look for the dosimeter. I used the same setup of fuel cell and syringe as you did, however I didn't find it convenient to store, so I preferred to fill a small bottle by having deuterium remove water, and I store it top-down with some water at the bottom. I then open it under water and pick a little bit of deuterium with the syringe, then I can close the bottle. The water at the bottom is enough to make it completely sealed. I'll look deeper into your voltmeter schematics, that could help me as well. I'm using small power with a tiny central sphere (~8mm) initially due to limited room, and it seems to allow me to run at low enough current. Good job!

[@TheExplosiveGuy]

That dosimeter is _really_ cool, it's so simple yet ingenious. I've been playing with HV again lately after a decade hiatus (got shocked, almost died, but now the gun shy has worn off🤣) and in my quest to make a 1.6KJ capacitor bank charger I've made a rectified variac-fed MOT (with a couple different switchable current and voltage options using a series of different wattage and voltage light bulbs in series with the primary, with a switch on each one) that puts out up to 3000V DC, and now it has opened up a slew of opportunities in magnetron sputtering, wood burning, and now fusors. I definitely need to build one of these albeit a lot simpler than this one, that chamber is just way too nice for my taste (budget😔😅). I have a cheapo $100 vacuum pump but I need something a little stronger for one of these too though, it doesn't make anywhere near enough vacuum from what I hear. Anyone got a spare diffusion pump?😉

[@henrikstenlund5385]

This is so nostalgic for me as I worked in 1980-1986 with TOF mass spectrometers I built. The pumps and instumentation were very similar. Can you make the DT reaction be more effective in the Fusor if you force the ions to move fast back and forth? Instead of using a DC HV, you could use an AC HV in the MHz range to keep the ions inside the reaction area? The ions would go again and again to the center increasing the reaction efficiency a lot ro overcome the Coulomb scattering. Just an idea. Good work people.

I've been doing amateur organic chemistry for close to 6yr now, and it's still incredible what you can learn online with a little reading. Great work though, this is on another level... I'm assuming your major is physics.

Thank you for the kind comment!! That’s funny how ubiquitous the chemistry supplies from that kit are that you were able to identify them, and neat that you had the same one!

I have fond memories of using the chemicals from the kit to do much more dangerous experiments that I found from reading online. They certainly weren’t recommended in the manual! I’m glad to hear that your fascination and hobby with chemistry is still going to this day. And you are correct, I did major in physics as well as chemistry as an undergrad.

Second where did you buy your bubble dosimeter, I can’t seem to find them anywhere.

[@ScienceMarshall]

I would recommend that you head over to the fusor forum at fusor.net/board/. You should spend many hours reading through the FAQ threads. Your questions have been answered there. My mistake early on was not spending enough time reading the forum before beginning to purchase components. There is a lot of knowledge, useful tips, and trial and error that have been documented there already. So it's best to learn from other people's success and mistakes! As far as the bubble dosimeters go, they are only sold by BTI Bubble Technology in Canada. The model I got is the BD-PND. You will have to contact them through email to make an order. Also the bubble dosimeter should be the last thing you purchase when you are completely ready for fusion as they have a limited shelf life.

[@jeromedavis7816]

I know this is a super late response but seeing as no one else said anything i thought I’d chime in. To answer your question no probably not, there would be too many other atoms in the way of the H-2 to cause consistant fusion. What you can do is use to fast neutrons produced by this setup to cause fission in a fuel such as thorium then use the heat from that to boil water and spin a turbine but at that point you basically have a fusion reactor powering a fission reactor which, while still cool, isn’t necessary since you can make a fission reactor without all the extra steps

So lets say 30kV and 2,5 mA, that means the outcome effect of this reactor is around 75 W? I’m new to this, does this generate power, or just a reactor that makes heat

Bet you 5 bucks he's on a watch list

cool!

It's nice to see this project work out. You should try to create some microscopic amounts of tritium using lithium-6. But I suppose you'll find it hard to get lithium-6. You will find out why if you look at the uses of lithium-6

[@notioncreanga]

you do know the half life of lithium-6 is under a second, right?

[@dankmemes6254]

@@notioncreangaThere is no half life for lithium 6. Did you mistake helium-6 with lithium-6 since helium-6's half life is under a second

[@notioncreanga]

@@dankmemes6254 Shit. Forgot that lithium-6 and lithium-7 are the only stable isotopes of lithium. My bad :)

If you distill the tritium out of the worn out car batteries ? Ron cheap recycling

Can you please tell me what classes you studied in order to learn this?

[@ScienceMarshall]

Most of my learning for this project came from the fusor.net/board forum and other internet research, not from classes.
