Hello Project Infinity, I'm a researcher and I'm currently doing research in fusors using different types of grid shapes and the application of magnetic fields. My paper will be published in a few months. I stumbled upon your channel and it looks like you have been doing some impressive work in this field as well and I have considered trying out out some of the shapes that you tried out as well, Keep up the good work, you will be cited in my paper.
my name might come off as imature old account mostly but im very very infatuated with this stuff i want to pursue it as a career path in the future more along the geneva lines (cern) but if we could chat at some point i wold like to conduct something like a interview just to gain much needed insight on this field of research if you arent for a interview all understood people can be weird online -Will
@@Project.Infinity Hey there, I'm replying after months because I was caught up in some other work and it took a lot of time to acquire the materials needed for this ( I live in a remote place) so I have started working on the actual build and I'm finalising some parameters for the calculation of the lorentz force. I would love to share the paper with you when I'm done with it, but that will probably take a few more months. My work is pretty amateur but thanks for showing interest!
F.Y.I, in my project, I'll be focusing on using magnetic fields to induce rotation into the plasma, the grid would resemble the 'tokagrid' which you used in your other video. It will have two sets of spinning concentric rings of plasma in opposite directions
Bear in mind please this is NOT a "Farnsworth/Hirsch" fusor. It's the "Hirsch/Meeks" variation, which is based on Farnsworth's overriding concept of Inertial Electrostatic Containment" It's been sixty years since anybody has built what could be rightfully called a 'Farnsworth' fusor. Still, it's cool that so many people are learning some of the particulars of what it takes to 'bottle a star.'
Oh wow, very interesting. Searching for more details about each design I found this discussion which was very helpful: fusor.net/board/viewtopic.php?t=13161 It seems you are spot on. Thanks for the correction!
looks totally like crystal from magic staff or a magic orb with loaded spell :D And I love that you mentioned of perfect plasma symmetry, it's actually not that hard, the magnetic forces equalize alot of your mistakes :D important part is coil symmetry and surrounding space.
Tungsten has the highest melting point of all metallic elements. This means it can withstand the massive amount of heat that builds up from ion bombardment better than any other known material. Thanks for the question!
Around 2 years ago when i was 14 i made a cathode ray experiment, now i rey want to build a fusor but cost of all equipment needed and precision is on anther level than jar, fridge compresor and ZVS circut fo r high voltage, in this point i can only provide good voltege source for the fusor and not much more so i porpably giv up on dhis project for now. I will probably come back to it in a few years and then films like yours will be worth their weight in gold
It's such an engaging and rewarding hobby. Hopefully you'll get back into it and I'll have more videos on the topic to share! Thank you for the positive feedback.
hey, I am planing on building a diy version of this kind of a fusor, but i have about a 12kv power suply and only about 5000 mtorr of pressure, would i at least get a glow mode out of my setup? + i have a cube like copper cathode and a ring like anode positioned over the cathode by around 3cm (can increase to 6/8cm if needed).
At that pressure you'd probably get glow discharge and see plasma surrounding the cathode wires. Your power supply sounds like it can supply more than enough voltage, but you'll only pull about 200V out of it at that pressure because there are too many air molecules which will drive the current up. I'm sure it'll look beautiful though!
@@Project.Infinity yeah, thanks for help, but you said my power suply would only draw 200v, but i am using a zvs driver + a flyback transformer, does that change anything? It is capable of 5 to 10cm arcs if i suply the zvs with 12v 17amp
@@lukisltu5282 No matter what power supply you use the discharge at that pressure will be low voltage. It might require a high voltage to initiate the discharge (similar to the 5-10cm arcs at atmospheric pressure), but once the discharge is initiated, the ionized gas acts as a conductor with very low resistance and high current. It's not exactly ohms law when dealing with plasma but you can think of it that way. It'll only draw high voltage from the power source once you remove air molecules (lower vacuum), increasing the resistance of the circuit.
Very cool demo. Are you willing to reveal the total equipment cost? If the cost and safety risks are low enough, this could be a profitable product for the educational market. Instead of just telling kids to study math, entice them with an interesting hands-on experiment that demonstrates a behavior which can only be fully understood by the math that you want to teach next. Hopefully at least some of the kids will then eagerly pursue the math in order to solve the mystery, and/or better visualize the math concepts because it connects to their memory of running the experiment.
Thank you! The cost varies quite dramatically. My setup has been built with mostly secondhand lab surplus equipment or custom built parts I turned on the mini lathe, so it's total cost is more reasonable. If I had to guess all parts in total would add to around $2000-3000 along with a LOT of sweat equity. Unfortunately the voltage and current are way too dangerous for kids to work on unsupervised, so selling these would likely be too much of a liability issue. My best suggestion for kids with an interest in the subject is to visit fusor.net and start with the basics. It's a highly rewarding hobby but it definitely comes with an expense
I'm afraid your Geiger counter is most probably not activated by radiation, but by electromagnetic noise, UNLESS it's properly shielded in a Faraday cage.
I did originally have issues with electromagnetic noise in an early fusor design that had a lot of breakdown issues. It was then that I confirmed x-ray production by shielding the Geiger counter with a grounded aluminum foil Faraday cage. I also confirmed x-rays by comparing the GM counter with a pen dosimeter. Much to my surprise the mR dosage absorbed by the dosimeter and calculated by the GM counter correlate pretty closely. With how fast the GM counter roars with high x-ray production I imagined it would saturate and give a false reading. I'm quite happy with its performance!
Thank you! I tried to capture it the best I could on camera but it's honestly even more spectacular in person. I've thought about wrapping the chamber with a coil and experimenting with electromagnetism but haven't tried it yet. I will also eventually be building a sputtering setup which uses magnets to concentrate the plasma on a target. I'd certainly make a video for either project :)
@@Project.Infinity both ideas sound spectacular if i could ask where did you get the education for this and how do you maintain such hugh video quality for a much too low subscriber count this content is fantasticaly detailed and quite thourough i will use a lot of the data in this video for my own projects and expirements thank you personally for helping inspire a whole new branch of theories and projects i can make because of you
My base of knowledge comes from physics classes in university. The vast majority of fusor specific information though I've learned by reading forums at fusor.net and published articles.
Right, there is no neutron radiation at all because there was no deuterium. There was a bit of X-ray radiation though generated via bremssrahlung. It's emitted when high energy electrons in a vacuum hit a dense surface. In this case the dense surface is the stainless steel walls of the vacuum chamber.
This is a complicated subject but the shape of the electrode actually doesn't matter that much. Check out Chapter 3 of Miley and Murali's IEC fusor design. It's not intuitive. But, it comes down to the ion mean free path being less than 3 cm.

Why having a tungsten grid?

Most people need about 5000 to build these. Mine is creeping towards that number too.

Have you considered using permanent magnets to further shape the plasma?

Wait a minute, I didn’t think radiation was still produced without deuterium

Your center electrode is all wrong. You want what looks like a wireframe soccer ball. A truncated icosahedron.
