emp Electro-magnetic Pulse ?

if u know anything plz post links
or what u know

how to buid an emp generator?
plz ans question
flux compression generator

THIS article explains it quite well.

But you can always google a bit on "EMP" ...

What article Zion?

You haven't censored it have you.

Click on the word, THIS, in his message. It's there.

Why do you want to know how to build an EMP emitter?

This article might have some of the information that you're looking for...

According to official documents of the Pentagon the technology is quite mature: There are 3 different systems to create such a pulse:
1/ The American army sees most potential in the Vircator using microwaves. HPM (High Power MicroWave technology) is pretty complex, but very powerful, en yet compact. Ideal to use in boms and cruise missiles. The weapon can be adjusted to different pulses of different frequenties.
2/ 2nd one: Magneto-Hydrodynamic Generator, is still in test fase. very large and heavy and not applicable in the coming years.
3/ 3rd one: Flux Compression Generator (FCG), most simple one. uses electric coil with inside some dynamite. Just before the explosion the coil is charged. Because of the explosion, the magnetic field is stronger and pressed together. So al lot of the explosion power is transferred to the magnetic field. The FCG is compact, easy to build but it can only produce frequenties below 1MHz.

If requested, I can post data later to protect yourself agaist a EMP or e-bom.

Please do, when you have a few moments!

An E-bom does a lot of damage to devices that consist of semi-conductors like computerchips. Metaloxide semiconductors like Ge or Si are very vulnerable to high voltages. Affected devices don' t work anymore like they are supposed to, or don't work at all.

The military uses more and more fiberoptics because fiber is very little affected by EMP. Ongoing research to realise an optical PC helps of course.

You need to prepare for 2 events:
1/the direct EMP-wave and
2/ the indirect consequences.
1/ the first one, World wide cages of Faraday (You know the guy who got struck by lightning) are used to protect important computer systems from magnetic interference, of which an E-bom is an extreme example. Think of it as a closed cage where current is flowing on the outside and everything inside is isolated from electric fields so you can barely hear your favourite radioshow. This cage is very expensive and only big companies and universities have them.

2/ the second one happens 15 minutes later and is much more sneakier. When a EMP hits an electronic device, local magnetic fields are induced and when those fields eventually collapse they transfer electric currents through the power and communication grid. Its�s like an aftershock. These currents damage other devices that get in their way. It�s ideal for terrorists who want to attack an well guarded place like a financial or telephone centre by attacking a connected unguarded building far away. Copper wires used in telephone lines conduct those currents unfortunately very well.

Decreasing magnetic interference inside electronic circuits is done by using a shield made of metal with a very high magnetic conduction which leads it away. A alloy used is mu-iron.

To be completely safe you put all your devices inside a cage of Faraday and cut all your connections with the outside world like electricity, telephone, cable, etc� Like living back in the stone age.

In Belgium a private company built a EMP-prove bunker where large companies can store their sensitive backups. If I find it, I will post the link to their website.

Check in popular mechanics. There awas a article in one of their magazines about E-bombs and how to makle them.
