Ok older bro had a smart idea of usen tig welder
Just borrowed cable from another welder so got a pos and neg cable
Tho had taken off the copper grids trying to get a spark between the wires
So will have to rebuild that part another day
But works got a good spark going
Just need to get it back to what it was to create some plasma
Prob be a few days

You will not create a plasma in air just applying a welder to those "electrodes". Also, a new picture would be helpful of the setup; also, maybe define what you are using for electrodes in the current setup.

I got a vacuum chamber and pump
And a bit of copper wire

Not 100% what to use for electrodes

Was just planning on wireing up the copper wire into a couple of rings with a small gap away from each other

Will get a few pics of finished setup up if get into work today to finish

Here’s a pic again of frame for magnets
Will be putting copper wire at base of magnets where zip ties are

Here’s finish

Going to soldier wires on then give it a go

How have electrically insulated what looks like the electrodes? It seems like they are connected by the aluminum frame. What is the goal here? Obviously fusion can't happen in 20 psi oxygen/nitrogen. Is this just to observe effects of plasma in the magnetic field? Are you planning on putting it under vacuum?

Well seen video of plasma being created nere a magnet on YouTube and plasma spinning around magnet which seems to be moving
Idea was to have plasma spin up from both sides because magnets have the like pole which repels/pushing away so in theory plasmas would be going different direction spinning around till met in Center and because magnets are close enough that there pushing away from each other hence why’s had them bolted down or would wana spin and attracted , broke one and damaged another putting it together anyway
wondering if it’s done the correct way with right gases might make fusion
I did see a video once that mentioned hydrogen and boron gas? , when fuse create alpha waves they turn into dc current when hit sertain metals apparenely
I did book mark but got made privateon youtube

Anyway taking a break
Imploded my vac chamber kinda
When I was lowering pressure noticed I hadn’t put lid in a safe position
And when got to -20 psi side that wasn’t over enough slipped, damaged the frame magnets where on.

Older bro managed to fix my vacuum chamber and prototype

I’m thinking of getting a 8kV neon transformer.
Would that be good enough for creating plasma.
Also if anyone could explain to me how to set it up inside vacuum chamber to make the plasma would appreciate.
Am a total newbie when comes to making plasma.

A 8 kV neon sign transformer (NST) will certainly create a plasma, even an atmospheric one depending on separation between the electrodes. But at lower pressure the plasma gets larger.

There are more ways to make a plasma than there are books, papers or even ideas on the subject. One method is just mount two nails using plastic posts (the posts will insulate the nails from the local area.) Have the nail points face one another with a short gap of 3-5 mm. Hook up a wire from each nail (using a clip) to each pole of the NST. Using a variac, turn up the applied voltage to the NST. At some point, the air will break down and you will have a local plasma in the air across the short gap between the nail points.

One does a similar process in a vacuum chamber but a cathode and anode (for direct current: i.e. the transformer has a diode or diode bridge) are often fairly large and separated by many centimeters because from 0.1 torr and 1 torr, it is very easy to 'strike' and maintain a very large plasma.

There are many posts of people doing this using "demo fusors". Look those up and see their pictures - it is very easy.

Aside: The pot you are using is very weak for any real vacuum work. Also, one makes the cover large enough so it can't enter into the 'chamber'. Don't cut the plexglass to just fit. Make the cover a few centimeters larger than the chamber lip.

hi

well i bort the vacuum chamber with lid off the net. so didnt have part in making the lid,
its a bit larger than vacuum chamber, just didnt have it on center when it imploded
