Although not an ion gun per say...plasma gun.

For the design and construction details of ion guns, necessary for more advanced designs and lower vacuums.

Hi there
You made reference to a wire suspended 1/2" below the arc. Did you forget this on your diagram? Also, how many volts should it be, and wouldn't it be more efficient to use one or two good magnets, positive side up?

Hi Liam:

That wire creates a mirror magnetic field that does the actual repulsion. To get a really good result the discharge voltage should be at least 2kv.

Sounds like a job for a Compulsator (compensated pulsed
alternator). These also look kind of cool for a Z pinch rig.

Serious current pulses from stored kinetic energy!
Just remember the reaction torque on the stator when the thing
is triggered!

Just dreaming!

So... has anyone yet constructed this device (besides Mr. Leins)? If so, please share the results!

i did, but i was not successful. i kept having mechanical issues with the carbon electrodes... i couldn't find a way to keep them secure. so, i got some nice arcs, but every time i discharged the cap, the electrodes would be blown out of the device.
i donno, is a .15uf 35kv cap to big?

Hi Q:

I would start smaller than that value capacitor.
To hold the electrodes really tight curtain tube rods work well.
Ive even used arc welding electrodes firmly mounted.
When using rod make a "v" with the two rods just like a jacobs ladder but space them so the arc stays put.
This way the recoil is less on the electrodes and the plasma flies away fast and hard.

Happy Fusoring!

thanks, larry!
i have been re-planning this expiriment... think i'll go down to a nice 90j cap instead. i'll also be using larger electrodes; the 3/16" carbon rod i was using seemed to detonate at the power level i was using. poor planning on my part.

I know this topic has been dead for a long time but what ever happened? Does anyone have any pictures or videos of one of these?

This whole thread risks deletion! This is not a fusion usable ion gun and therefore is under consideration for deletion. I'll give a day or so and all the thread is probably gone. Fusion related guys and fusion only. This is not a fireball cannon DIY site.
