Re: Voltage level for static E-feild

The path doesn't need to be long, from one end cap to the anode will be 1mm or less, or just don't want a arc discharge.
Thanks

Re: Voltage level for static E-feild

Thanks you two for the info. S_Sesselmann would that arrangement work without the difference in pressure?, what voltage level could it be with the right pressure variables? I've added the idea to the drawing its a easy voltage doubler, and plan on useing a Rocker 300, 220V/50Hz oil free vacuum pump ...

Voltage level for static E-feild

Hi, I'm trying to make a ion gun, and was wondering at what voltage level would a 0.5mm needle emit electrons. Was planning to run it in a vacuum of about 0.1-0.5psi with a gap to target of 0.5-1mm. I can get access to a 250nm UV lamp and was wondering if that would lower the threshold, and if the g...

Re: air scram jet

Hi Andrew Robinson If you could find out the specs or a picture, I might be interested(for another project not related to this). About other stuff I'm not ready to build a fusor anytime soon, unless inspiration strikes with a new idea. Hi Monroe Lee King Jr I haven't run over the numbers for the des...

Re: air scram jet

Hi Ross Moffett
I was thinking about making my own, 1cm thick AL,1m3 with barium titante at 1cm spacing is about 1uF, I think it should reach 100kv, at low resistance it should put out the amps, but not over a long time.

Would 1uF be to small?

Might make some interesting plasma physics experiments.

Re: air scram jet

Hi Ross Moffett The wire would be large enough, spec out some 640mm2 AL wire that can handle 8kamp steady state about 0.02ohms/meter. Hi Richard Hull I'm work on a power system that might be capable of that current at 10khz, high voltage with a small cap, the induction of the coil will limit the cur...

Re: air scram jet

Hi Rich Feldman

10 Turns
0.1 m length
0.25m3 radius
100,000amps
0.9 permeability
11.3 Tesla Yeah abit short :(

I was thinking 100hz to 10khz switching

Re: air scram jet

Hi Richard Hall
:)
The 3000K is just to get plasma, if you have say 10 turns of wire around the chamber with 100kamp going through them It would compress the plasma. What would it be if you have 10Mtelsa. The z pinch operates by compressing.

air scram jet

Hi this is a basic design of a scram jet, the pressure from one chamber, increase the velocity of the first/second chamber velocity. As the pressure increase the same pressure get changed into velocity to sucking the income air and the cycle repeats, untill it blows. Was thinking that at 14Mv(past b...
