Hi Folks:

Warning: This is illegal outside of a farraday shielded box.
I used a microwave oven as my faraday shield box.
If people are interested I will post photos and a complete set of instructions. If you're gonna do it anyway.. stay far away from the device... induction fields will cause the case to rise in voltage rapidly during disharge. Death can result! Remote it all!
This is a how to on High energy Radio Frequency or HERF for short. With all the caps and stuff for pulsing around ,I just can't help doing improptu experiments. One that worked very well was
a very simple experiment where you put a wire at the end of two insulators and explode the wire. Tons of rf. On the radio. Cool.
Then came the really irrational part...humm wonder if I can focus it...yep used a mixer bowl to focus the rf/emp.
The length of the wire equals the half wavelength of the rf to be generated so I took an quarterwalength of the bowl's opening as my wire length.
I could focus the rf beam into a 3 inch circle.
So If I use a 12" mixer bowl and reduce the focus to 3 inches.
That is a power increase of 4:1...So If I create 100J worth of
Rf ...I get 400J at the focus ...Neato.
Now comes the High energy part...discharge it in a microsecond
100 Joules becomes 1.00 x 10^8 Watts or 4X10^8 Watts RF at focus. Loads of power for an pulsed accelerator.
Want it continous?
I thought I would never use this stuff outside the military.
Replace the wire with a marconi style emmitter.
Pulse at will.

HERF Stuff
Re: HERF Stuff
This is sounding very interesting... Could you post ALL the info before you get visited by people telling you not to? 
Re: HERF Stuff
Hi Kerry:
You can visit http:/www.amazing1.com and see the emp/herf shock pulse machine in diagram form.
The one pictured runs at 100 kv.
They are incredibly simple devices.
A cap ,spark gap,high voltage supply, a small piece of tungsten wire (igniter wire - most bang for the buck)
The dish is plain jane Walmart style mixing bowls.
It is your "parabolic" reflector.
I'm fairly cheap...could buy a lot o stuff for 40 bucks.
The "test chamber" is a defunct microwave oven.
Remove the cover .
Remove all electronics inside.
Save the interlock safety switch for later.
Put in a high voltage supply. (working voltage)
Big cap for the triggering 150 uf@ 400v
Automobile ignition coil
HV Capacitor (flavor to taste)
Ross HV Relay 15 kv to prevent house spikes (I like my computer gear.)
12 volt transformer
You could use overvoltage gaps but I'm a control freak when hv bang is involved
Spark gap (trigatron)
door bell button.
Remove the magnetron.
Run all high voltage leads through the magnitron opening.
There is a plastic cap at the end of the magnetron feed hole.
Remove it and drill two holes for the hv wires.
fead in the wires tread thru cap ...replace cap in the feed hole.
put on the cover
ready to rock.
It is a weekend kind of project
My Herf runs at 10 kv
My trigger coil spark gap and cap are on the right wall.
I used cable ties to hold capand spark gap downto a wooden panel.
The auto coil is bolted to the wall.
The reflector is on the left
I have a remote box to trigger the device.
Operation goes like this:
Close the oven door.
raise the hv relay to connect the cap.
Charge the cap. ( less than a minute for 2 UF @ 10kv)
Disconecct the ps
Short the ignition cap with the door bell on the remote panel.
Spark gap disharges.
Wire blows.
Simple.
I will post a picture of the gizmo.
Happy Fusoring!
