I forgot to mention in the video, that my take on a fusor was partly inspired by Will From London's fusor! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EVOBk-InL00.html. Thanks for your assistance, Will. Also, dont attempt a fusor unless you have some shred of what you're doing, they can be dangerous.

Hey heads up, that reactor is probably not safe for fusion. The big acrylic windows could melt in the electron beams that form and the plasma heating them up. Also the aluminum frame and acrylic windows are transparent to xrays so it needs to be fully encased with shielding or it'll spew xrays like crazy. And you need neutron shielding as well. And even the backscatter can be very very dangerous. It's a grogeous demo build for sure though. One of the nicest I've seen honestly. But please don't try running that at fusion temps. Also there are a host of different laws around building these and many places require a license of some flavor or another. It's easier in the US, but varies state to state and can still have issues if you're not careful and you'll be posting the video as evidence of you doing it... so better safe than sorry. I know this because I almost built a working fusor on my channel recently but stopped when I learned about the license and 100K fine for not having it. So I paused the project until I could sort that out and get the license in advance. If you wanna chat about this I've been at it for years and might have some tips. Hit me up. There's a ton of amazing things that can be done with this if you get reasonable neutron outputs.

@putinscat1208 Год назад

For small amounts of fusion, it would be OK. But plasma constantly generates braking radiation. So those big plastic windows are a problem. D - D fusion is possible by slamming deuterium into a deuterium target. This was shown in the 1930s. You can't get more energy than you put in, but they made He-3 in the process. I'd love to see someone make a plasma and then slam it into something.

Awesome work Jay, that's one heck of a sight! Have you considered tritium breeding to get your tritium? If you throw a small amount of lithium into your reactor while it is running off of deuterium, any neutrons that are produced from fusion will be absorbed by one of lithium's isotopes, resulting in transmutation into tritium, which will exponentially boost fusion rates!

@vylbird8014 Год назад

I thought id just mention this here real quick for anyone attempting a simmilar experiment. A fusor emits strong gamma radiation due to bremstrahlung caused by the decelerating electrons & gas ions. Standing next to an operating fusor for extended periods of time is significantly more dangerous than any x-ray scan or anything the like. I recommend using lead plates to protect youself as well as keeping one geiger counter, preferably scintillation based, on your person as well as one with the fusor.

@guytech7310 Год назад

I've built a working Fusor: 1. A PVC hose is not practical for a low vacuum system as it will outgas preventing you from getting down to a very low pressure. 2. If your vacuum pressure is low enough you still generate x-rays which should be detectable by a gieger. I suspect your pressure is no where low enough. 3. You really need a better vacuum gauge, one that is designed for sub micron pressures. 4. you really need a much larger diameter vacuum connection. At least a half inch, and keep the connection between the pump and the fusor as short as possible. ie put the fusor on top of the pump so its just a few inches away. At low pressure the pump will struggle to get air out of the fusor's vaccuum chamber. bigger diameter piping will help. Ideally make it all metal piping to avoid outgassing from plastic. Copper tubing with compression fittings is a better option than plastic tubing. 5. I think you likely to suffer a voltage drop with the large electrode. the more current flows it will drop the voltage well below the 40KV. You probably running less than 10KV, which is also why you don't measure any x-ray radiation. Very low vacuum pressure + smaller electrode will reduce your voltage drop. 6. Your plexiglass\lexsan windows will outgas a lot, likely preventing you from getting very low pressures. Ideally I would replace them with glass and mount the electrode through the stainless metal frame. You need some sort of HV vacuum fitting. You might be able to get by with a spark plug, but thats iffy at +40KV as it likely to arc over since there isn't much distance between the electrode and the metal frame on the inside side. You might be able to weld on some wire to the spark and pass it through some glass tubing with some vacuum grease and some teflon tape. Teflon is a great insulator & does not outgass. Alternatively you can buy a HV electrical vacuum pass through from or Kurt J Lesker (company). "LDS vacuum shopper" also sells vacuum components at a lower cost than Lesker. FWIW: You best way to get an operational fusor is to go with commerical vacuum components, specifically conflat vacuum components and metal (copper gaskets). You could buy a Conflat Tee with one port for the vacuum pump, one for the HV feedthrough and the other for the window. The big cost is going to be a HV feed through as a 60KV feedthrough will cost about $2k. Maybe you can get lucky with a 60kV feedthrough on ebay (ie used) to save some money. The biggest issue making a working a working fusor is the cost of components or the time collecting used components on eBay at a reasonable cost. I probably spent over $10K in components to make a working fusor & also did a lot of self fabrication (ie machining & welding Stainless Steel parts for the vacuum chamber and welding on conflat flanges), $3K+ on a turbo molecular pump and a high volume low submicron mechanical pump $1K. I think I spent about $1500 on the 60Kv high voltage feedthrough (purchase about 20 years ago), vacuum bellow hoses, oil backstreaming trap. As well as assortment of radiation measurement tools: BF3 & He3 tube to detect neutrons, NaI Scintillation detectors. Building a working fusor isn't easy nor cheap.

@RTL_CSQ Год назад

Amazing work! A few tips: Helium from a balloon filling tank is usually 5% N2, which is probably why the plasma color was a bit off. At these pressures and temperatures you'll have to start worrying about outgassing, so you may want to ditch the vinyl tubing and acrylic plates (heresy, I know) for thick glass. Putting JB weld on the outside of leaky fittings and using barbed connectors can trap small amounts of air and slowly release them into the chamber. You won't notice the pressure changing much because the pump is balancing the very small leaks, but it can ruin the purity of the deuterium gas needed for fusion. I prefer fittings with an o-ring like KF fittings, but they can be pricey.

@PlasmaChannel Год назад

Thanks Nicholas - yeah my helium tank was actually 10% oxygen, so that also complicates the matter further! Good notes on the use of tubing too.

@WaffleStaffel Год назад

@@PlasmaChannel The bigger pump is probably compensating for the tubing and other sources of leaks/outgassing, but I'd definitely switch to a better tubing. HVAC people use special large diameter multi-layer hoses ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b8j85R9xvMM.html) to get down to 500-100 microns. Also, the needle on your gauge can go down to the stop and you can still have 20,000 microns. You really need a thermocouple micron gauge to determine that. Keeping fresh oil in the pump is essential for good vacuum. HVAC people change the oil in their pump every 2-3 uses to get a deep vacuum. I'd also switch to loctite and dielectric/vacuum grease, and even dismantle the ball valve and smear grease on all the seals and surfaces (I did just this thing a few days ago). But again, that giant pump running continuously is going to compensate for a lot of that, especially with such a small evacuated volume. Awesome video, can't wait for the next one!

@RMX7777 Год назад

@@WaffleStaffel to add to this, unfortunately the pump he has likely isn't going to cut it. You might get fusion to occur under 30 microns, but you really should be looking to keep it under 10 microns if you want to have good results. The vacuum reading on your pump should be ignored. The pump is reading the vacuum level at its inlet, but there can easily be over a 1000 micron difference between the inlet of a pump and the actual reaction chamber. The only way to know for sure is to install a thermocouple gauge directly to the reaction chamber. I would recommend using one of fieldpiece's products like the svg3. I don't want this to come off as negative, I would love to see you succeed in your project.

@cberge8 Год назад

The vinyl tuning between the pump and your chamber was probably a big factor in why you couldn't reach a higher vacuum. Vinyl tubing tends to off gas way too much under vacuum to get down to the levels you're looking for.

Tubing is only one of many issues, those HVAC pumps wont get anywhere near low enough. You would need to switch over to a diffusion or turbo pump.

Wow this is ridiculously awesome! I've marveled at quite a few fusors like this that other people have built but your version looks the most ready to be a showpiece. 95% of this stuff is over my head, but the one very minor thing I thought you might be interested in knowing is that when applying PTFE tape generally you want to wrap the tape clockwise (to match the direction that you will rotate the pipe/fitting). Also, for gas/vacuum applications I believe the standard is 4 wraps of the yellow gas PTFE tape so I think you would need 8 wraps of the white tape. I'm quite surprised you were able to get away without using hose clamps on the barbed fittings too!

Real fusors pull vacuum down to at least 1X10^-5 torr before introducing deuterium, as any air impurity will make fusion pretty much impossible. They also need to be made of steel, If you make it out of glass it will just act like an x-ray tube, irradiating everything around it.

@martinfyhn1976 Год назад

I'll be really impressed if you can get a hold of tritium, as it's incredibly rare and expensive (it has a really short half-life), but deuterium should be enough, if you want to make fusion. But it's a really good-looking build! 😁 As you've undoubtedly found out by now, to achieve a high vacuum, how much materials outgas, is really important, which apparently is one of many reasons that JB-weld is such a good seal (I have no access to the stuff). Acrylics outgas a fair bit, which is why it's not ideal. Glass is the way to go. HDPE (high density polyethylene) is surprisingly easy to get, and doesn't outgas very much (as in - I get so far down in my primarily HDPE and glass vacuum-chamber, that my electron gun stops working. HDPE hoses are also readily available everywhere. I *am* using a few silicone seals, which I can tell when I switch off my pumps, and leave my chamber at a vacuum. When you have something that outgasses, interestingly, you can see the pressure rise, over a few days, to a specific point, where it then stabilizes, and from that, it's pretty obvious that silicone outgas quite a lot (if it continues to drop, there's a leak, but that's usually obvious within minutes).

Are you even allowed to trade Tritium without an enormous amount of paperwork and a high security clearance? It's an radioactive isotope and used for H bombs?

@martinfyhn1976 Год назад

@@erikkarsies4851 I have no idea about that, but even if it's a component in h-bombs, it's not the primary one. In fusion reactors, they're working on tritium "breeders", which, if memory serves, is lithium. I can't recall the process, but they're supposed to create tritium, when struck by a neutron. But each deuterium-tritium fusion reactor, might need tritium to get started, and I've heard/read rumours, that there might not be enough for that (I have no idea of the reliability of that, though). If memory serves, tritium is also a byproduct of fission-reactors, which is likely our main source of it, but because of the half-life of it, we never have more than around 20kg of it on the planet, at any point in time - as far as I know (sorry for all of the uncertainty in this message - it's not the part of fusion I've studied the most - so for anyone who spots mistakes here, please don't hesitate to correct them).

@erikkarsies4851 Год назад

@@martinfyhn1976 Tritium is a very important component of Hydrogen bombs. It is used with Deuterium to turn the fission reaction in to a fusion reaction which makes the bombs much more powerfull. But I see on wikipedia (and I quote from there : "Tritium is an important component in nuclear weapons. " ) that is used for some other applications also. The clips I've seen of real working fusors until now were mainly inside scienctiric nuclear research locations. And I suspect there is at least an amount of bureaucracy involved using the stuff for experiments. The breeding of Tritium out of Lithium is a very tricky one because you need a neutron source (for instance a nuclear reactor) and those neutrons need to hit the lithium at certain speeds and even than it's a very difficult to extract the tiny amounts of (pure!) Tritium out of it. If you want to know more about it then the wikipedia of Tritium is a good way to start.

@martinfyhn1976 Год назад

@@erikkarsies4851 Thank you for the explanations and clarifications. I still don't know about the requirements of getting tritium, and initially I was thinking that I don't really see any reason to regulate it, as it's likely nigh impossible to get a hold of, due to rarity, and price, and because tritium itself isn't really dangerous, though radioactive. What I meant with it not being the main component of an h-bomb, is that you also need to get enriched fissile material, which *definitely* is difficult to get your hands on, and very regulated. I was also comparing it to deuterium, which as you mentioned, is another component of such a bomb, but is easy to get your hands on - but then I remembered another fusor video I saw, with someone who had a pretty difficult time of getting deuterium gas. He managed to get some, through working at a lab, if memory serves. Another youtuber in stead got a hold of heavy water, which seemed to be easier to get a hold of, and got deuterium through electrolysis. And then there's the fact that 10% of the ocean is deuterium. What I'm trying to say, is that if deuterium is regulated, then tritium is likely regulated in the same way, in addition to being really rare and expensive. I don't think that it's as heavily regulated as e.g. enriched uranium, but it is just naturally difficult to get a hold of. Also, many things can be components of deadly things, but it would be silly to regulate things that themselves are not dangerous. To exaggerate, it's sort of the same as saying that we need to regulate oxygen because it's a critical component of most explosive reactions.

@erikkarsies4851 Год назад

@@martinfyhn1976 One in every 6420 Hydrogen atoms in sea water containa an extra neutron (which means it's a Deuterium atom) so 10% is a bit optimistic, but indeed Heavy water is widely availabe and way cheaper than the 30.000 dollar a gram which Tritium was going for in 2000 according to wikipedia. I don't think the posession of Tritium is the issue but I would expect that goverments wants to keep track of the trade in the stuff. It isn't really usefull to regulate Deuterium because it is so easy produceable compared to Tritium and so Deuterium isnt an issue in the balance of power between super powers The problems you describe with Deuiterium probably have to do with purity and nature had a long time to produce Deuterium while Tritiium has a half life of about 12 years. So you won't find much of it naturally. What I do know is that the superpowers are not open about the amount of Triitium they have as a strategic stock which does signal some nervousness poltically about it. Deuterium isn't radioactive and Oxygen is neither. And in many places you can pick Uranium which you could theoretically turn in to fissile material. Still they are quite worried of countries like North Korea and Iran doing exactly that. I sure don't think they would like that those countries would buy considerable ammounts of Tritium. If they would find a easy way to produce Tririum a lot faster they probably first even would try to keep it a secret if they can.

Yeah I think source of the issue was the Teflon tape and lack of hose clamps on that tygon tubing. If it was straight brass on brass it would have been much tighter and easy to undo. Also a digital gage could help you see much lower pressures. I've done some work that needed some ultra low vacuum for some cryogenically cooled radiation detectors that fail with the slightest atmospheric impurity.

@CharlieSolis Год назад

Did you have to go through the process of electro polishing the inside of your vessel?

@CharlieSolis Год назад

For anyone looking to make something in the future, stainless steel kegs are vacuum capable and are electro polished on the inside and are great for use with nuclear fussors. A couple of universities have done this. ASU has a couple videos going through their process of turning a keg into a nuclear fusion chamber.

@PlasmaChannel Год назад

That’s awesome. Thanks for the info! No, I did not polish mine.

@CharlieSolis Год назад

@@PlasmaChannel You’re very welcome! And thanks for the reply! The ASU keg nuclear reactor vacuum chamber videos really helped me for my vacuum steam Tesla turbine system build. If you’re positive it’s sealed But not getting a low enough vacuum I would guess that you’re off gassing from the internal surfaces. You may have to pump it down, hold it, pump it down again and hold it, do that multiple times over a day. All the micro crevices have gasses trapped and molecularly adhered to the internal surfaces of the chamber and can take a long time to get out if not electro polished. Another thought, 🤔 and this is just a wild stab in the dark because I can’t remember what your clear window material was made of, but the radiations, UV and otherwise, might be causing the window to break down and off gas too 🤷‍♂️ idk, I usually try to stick to stainless vessels personally with Boro glass windows, which you might have and I just missed it 😅 Hope some/any of this helps with your journey! Again, thanks for the reply!
