Buy Electromagnetic Pulse _VERIFIED_

Whether caused by man or nature, electromagnetic pulse (EMP) and geomagnetic disturbance (GMD) events have the potential to disrupt and permanently damage electrical components and entire systems within most critical infrastructure sectors and impact large-scale infrastructure. While EMP hardening standards exist for military applications, they are often too case-specific, expensive, and impractical for the private sector to implement, leading to very little action being taken to address this threat, despite it having the potential to affect the nation at large.

EMP stands for electromagnetic pulse. It can be produced by a nuclear detonation, a lightning discharge or any type of a discharge that can take on a form of a pulse with a fast rise time. Obviously a nuclear air burst produces EMP by releasing intense gamma ray radiation into the Earth's magnetic field where now a myriad of radio frequencies is generated due to the fast rise time and other Fourier properties. These type of pulses Occur and cause wide spread damage to many electronic circuits. computers and similar circuits are very vulnerable to this type of energy as it does not take many volts applied across the junctions of these high-speed circuits to disrupt their operation. When the EMP pulse contacts the printed circuitry of the system, a standing wave of voltage is produced and damages the circuitry components causing destruction.

A lightning discharge can be characterized as a natural manifestation of an EMP pulse. It is in the form of a double exponential pulse where the risetime is very fast and the decay time is much slower. The discharge current of a lightning bolt could be close to a mega Amp. This combined with the risetime of the current pulse can cause damage as we all well know. The overall charge of a lightning bolt is usually in from 1 to 50 coulombs. The discharge voltage being in the hundreds of thousands creates an energy pulse in the megajoules. Joules = coulombs times voltage.

Low powered hand held pulse gun generates EMP electromagnetic pulses capable of de-programming and disrupting micro processor circuitry. Gun is built in a pistol configuration where the 8 "AA" batteries are housed in the butt section along with the push button trigger switch.

Directional device has adjustable pulse rate control and a built in emitter for close proximity applications. Specialized circuitry use our ultra low inductance high energy density capacitors with self triggering gap switch. Charging circuit uses our loss-less inductive charging and eliminates the losses associated with simple resistive methods. Pulse energy is approximately 1 Joule with a rep rate up to 30 pps. Charging voltage is over 5kv with a peak current of nearly 1000 amps now equal to a 5 megawatt pulse of power.

We now have assembly schematics, instruction booklet, 20 colored photos of construction, and other data for those wanting to build a medium- to high-power pulse source. Plans show using the latest fast-discharge 100kV high energy density capacitors capable of 1500 joules energy storage. Discharges up to 80kV depending on utilized spark gap. This energy is switched using the latest triggered spark switching technology providing very steep rise times at multi-gigawatt peak powers. Included data shows Current controlled programmable charger, Trigger circuitry, Discharge circuit and all other necessary data. Antennas and wave guides are shown.

The Marx output of 90kV to 160kV pulse is fed to a peaking capacitor of 30pf to 180pf for shaping the pulse. The output peaking gap is fixed to shape the pulse further. The Marx now charges the output capacitor. This capacitor (coaxial oil filled capacitor) discharges into the load through the peaking gap. The entire system is coaxial made further enhancing the effectiveness.

The EMP pulser with a special Antenna is capable of shutting down a computer at a distance of 15 meters. It generates a steep 2 nanosecond rise time >2 Giga-watt pulse into a parallel plate transmission line type of Antenna.

The "EMP Blaster Gun" is suitable for many small experiments requiring radiating EMP waves. The system utilizes a high voltage discharge of 100kV to 160kV at a pulse repetitive rate of 1pps. It can also ignite highly explosive fuels in close proximity or contact.

These low inductance capacitors are excellent for EMP shock pulse generators, Lithoscopy, exploding wires, Marx impulse generators, Slapper detonators, plasma focused neutron enriching, gas discharge lasers, thermonuclear research, high magnetic fields, etc.

The most important part: In a spark gap transmitter, a lot of the design goes into blowing the plasma away and interrupting the spark. A hot plasma has a fairly low resistance and will remain conducting between the 120 pulses per second from a 60Hz AC arc welder. So some noise, yes, but strong oscillations, no.

Its interesting to note that my idea of a simple LED based photosensitivity tester based around LED strips harvested from old broken laptop panels could work here, simply put a low value resistor across each 4 LED bar to reduce the intrinsic capacitance and achieve minimum pulse width.

A lot of the issues listed above were concerned about collateral damage. Any good EMP device needs to be focused. Who wants a gun that shoots all over the place. A bullet or pulse needs to go where the firing device is pointed.

A favorite device for science fiction and action movie writers is the EMP generator. An EMP (or electromagnetic pulse) has the power to knock out all electronic devices within its range. Be careful because this could be dangerous. Supervise your kids if they want to try their hands at this.

An electromagnetic pulse (EMP), also a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. The origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current. The electromagnetic interference caused by an EMP can disrupt communications and damage electronic equipment. An EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering.

In modern warfare, weapons delivering a high energy EMP pulse are designed to disrupt [2] communications equipment, the computers needed to operate modern warplanes, or even put the entire electrical network of a target country out of commission.[3]

A pulse of electromagnetic energy typically comprises many frequencies from very low to some upper limit depending on the source. The range defined as EMP, sometimes referred to as "DC to daylight", excludes the highest frequencies comprising the optical (infrared, visible, ultraviolet) and ionizing (X and gamma rays) ranges.

The waveform of a pulse describes how its instantaneous amplitude (field strength or current) changes over time. Real pulses tend to be quite complicated, so simplified models are often used. Such a model is typically described either in a diagram or as a mathematical equation.

Most electromagnetic pulses have a very sharp leading edge, building up quickly to their maximum level. The classic model is a double-exponential curve which climbs steeply, quickly reaches a peak and then decays more slowly. However, pulses from a controlled switching circuit often approximate the form of a rectangular or "square" pulse.

EMP events usually induce a corresponding signal in the surrounding environment or material. Coupling usually occurs most strongly over a relatively narrow frequency band, leading to a characteristic damped sine wave. Visually it is shown as a high frequency sine wave growing and decaying within the longer-lived envelope of the double-exponential curve. A damped sinewave typically has much lower energy and a narrower frequency spread than the original pulse, due to the transfer characteristic of the coupling mode. In practice, EMP test equipment often injects these damped sinewaves directly rather than attempting to recreate the high-energy threat pulses.

An EMP arises where the source emits a short-duration pulse of energy. The energy is usually broadband by nature, although it often excites a relatively narrow-band damped sine wave response in the surrounding environment. Some types are generated as repetitive and regular pulse trains.

An ESD event can damage electronic circuitry by injecting a high-voltage pulse, besides giving people an unpleasant shock. Such an ESD event can also create sparks, which may in turn ignite fires or fuel-vapour explosions. For this reason, before refueling an aircraft or exposing any fuel vapor to the air, the fuel nozzle is first connected to the aircraft to safely discharge any static.

Simple electrical sources include inductive loads such as relays, solenoids, and brush contacts in electric motors. These typically send a pulse down any electrical connections present, as well as radiating a pulse of energy. The amplitude is usually small and the signal may be treated as "noise" or "interference". The switching off or "opening" of a circuit causes an abrupt change in the current flowing. This can in turn cause a large pulse in the electric field across the open contacts, causing arcing and damage. It is often necessary to incorporate design features to limit such effects.

Electronic devices such as vacuum tubes or valves, transistors, and diodes can also switch on and off very quickly, causing similar issues. One-off pulses may be caused by solid-state switches and other devices used only occasionally. However, the many millions of transistors in a modern computer may switch repeatedly at frequencies above 1 GHz, causing interference that appears to be continuous. 041b061a72
