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 Folks:

A few years ago I read a book called Temperatures High and Low reprinted by Dover books. In this book were many arc powered gizmos. But the one that caught my eye was was the plasma gun. It turns out that this device is a WW2 device turned up by Operation Paper Clip. It is a little known curious device..
not as famous as say a V2 Rocket or Jet Planes.

"German electromagnetic cannons were retrieved by the Combined Intelligence Objectives Sub-committee in 1945, which reportedly were capable of firing lightning balls into the atmosphere (8),"

Some one was kind enough to put the diagram into the High Lo
Book. It is simple as pie. When I was 13 years old I got kicked out of science fair for bringing a homemade arc furnance to school. A coupla years later when I was 15 I took the diagram and build a plasma spitter gun. The one I made could shoot plasma up about 3 feet. I used a motor starting capacitor .
Latter reading about the fusion ball experiments I tried high voltages.... Ball went higher. It was a good start into Ca experiments.
This is as bright as a arc welder so eye protection is needed.
Operating instructions strike an arc by almost touching the carbons. Pull the arc out to 1" discharge path.
The wire that runs below the arc (1/2" below) creates a standing magnetic field when the cap discharges through the arc.
It repells the plasma in the arc away at high speeds.
Carefull to move away from the device ...the balls burn hard.
Put a metal sheet in the yard to prevent fires...wish I'd thought of that.
The arc is run by a 1000 volt 350 amp Altronics special rectifier hooked into one line of the 110 volt line.
I used 10 kv as my driving voltage and a automotive coil to trigger a spark gap.
That gap is as loud as a 12 gauge shotgun.
Being in the county has it's little charms.
I used a light dimmer and 110 volt moter starting cap hooked to a automotive coil. The blocking caps are 470 pf @30 kv to keep high voltage out of the line. The coil will need'em too.
You need a remote trigger unit as these flaming plasma balls can be shot up 10 feet depending on the voltage. The balls last about a second or two after they reach their zenith.
If you want to keep your house don't do this indoors.
All high voltage concerns apply here plus noise ,blinding light.
Like a coin crusher .
Right up our alley Huh?
This is not a toy....be safe and not sorry.

Larry, i think you forgot the diagram. Sounds interesting though.

Hi Adam:

Just finished it.
I will put more details in shortly.

Larry,

Do you have any more details? The Power Point files looks like it was choked off.

Hey Larry,

I am in deep s**t!! The wife caught me "borrowing" a couple of flower pots and the brass curtain rail in the living room. Could not think of suitable excuse! Ah well, back to the workshop...

Cheers, Peter Hammond

I used to make 120V carbon arc lamps using two pencil leads in series with a hair dryer for current limiting. You could use that with a diode to make the arc then pulse the deflection circuit with a capacitor bank. Sync it all to 60HZ with a rotary spark gap and make it a full-auto plasma machine cannon. Use a small Tesla coil or voltage multiplier circuit to start the arc (like a TIG welder), make the hair dryer fan motor the sync RSG and fit it all inside the case. I can picture it now - the full-auto hair dryer plasma cannon.

I searched everywhere on the net for this thing. Cant find hardly a thing. You would think there would be some sort of amateur effort into a contraption like this(kinda like those microwave oven plasma balls).

Larry, how well does this thing really work. Does it shoot up a well defined spherical plasma or just a ragged flame ?

Eek! This is killing me... what is on the left? It's chopped off!!!!
Also, where can one find a copy of that book?

Also, am I correct by saying that this is just a capacitor that arcs between two pieces of carbon? That would solve what's on the left.

Hi Guys:

You can get that book at http://www.alibris.com
.
The part on the left is a straight line plug to the wall.
The original used a salt water rectifier made from a mason jar.
But today you can get high amperage diodes from Altronic for a few dollars.
It shoots up fire balls...spherical hot and nasty.
Tried to get a temp once with a glass thermometer melted the tip.

The book is very cheap($ 8.95). I just ordered one. Here is the link.

Are the fire balls 'FIRE' or are they 'PLASMA' ? It would be a shame to put effort into making an expensive Roman Candle.
