Shock wave generators are capable of producing focused acoustic or electromagnetic energy that can break up objects

such as kidney stones and other similar materials. EMP generators can produce pulses of electromagnetic energy that

can destroy the sensitive electronics in computers and microprocessors. Destabilized LCR circuits can produce multi

megawatt pulses by using an explosive wire disruptive switch. These high power pulses can be coupled into antennas,

conic sections, horns etc for very directional effects. Research is currently being undertaken to disable vehicles thus

avoiding dangerous high speed chases. The trick is to generate a high enough power pulse to fry the electronic control

processor modules. This could be a lot simpler if the vehicle was covered in plastic or fiber glass rather than metal. The

shielding of the metal body offers a challenge to the researcher to develope a practical system. A system could be built that

could do this but would be costly, large and could produce collateral damage to friendly targets.

EMP/HERF Multi-megawatt PulserObject: Generate a high peak power pulse of electromagnetic energy for testing the hardness of sensitiveelectronic equipment. To explore the use of such a device for disabling vehicles by jamming or destroyingcomputerized control chips. Experiment with disruptive LCR circuits focused acoustical shock wave concept

Hazards: The project uses deadly electrical energy that can kill a person instantly if improperly contacted.High energy system uses exploding wires that can create dangerous shrapnel like effects. Discharge of thesystem can severely damage nearby computers and other related equipment.......

Theory: A capacitor (C) is charged from a current source to an energy over a period of time. Once it reaches acertain voltage corresponding to a certain energy level it is allowed to discharge quickly into a resonant circuit.A wire now is made to explode disrupting this high peak current thorough the circuit inductance. A powerfulundamped wave is now generated at the natural frequency and associated harmonics of this resonant circuit.The inductance (L) of the resonant circuit may consists of a coil and associated lead inductance along with theintrinsic inductance of the capacitor that is around 20 nanohenries. The capacitor of the circuit determines theenergy storage and also has an effect on the resonant frequency of the system.

Radiation of the energy pulse can be made via a conductive conic section or a metal horn like structure.Some experimenters have used lumped half wave elements center fed by a coil coupled to the coil of theresonant circuit. This 1/2 wave antenna consists of two 1/4 wave sections tuned to the resonant circuit fre-quency. These are in the form of coils wound with an approximate length of wire equal to a quarter wave length.The antenna has two radiation lobes parallel to its length or broadside. Minimum radiation occurs at pointsaxially located or at its ends. We have not validated this approach!

A gas discharge lamp such as a household fluorescent will flash brightly at a distance from the source indicat-ing a powerful directional pulse of electromagnetic energy.

Test System Ref fig 1Our test pulse system produces conservative multimegawatt electromagnetic pulses (1 megawatt of broadbandenergy) and is radiated preferably via a conical section antenna consisting of a parabolic reflector of 100 to 300mm in diameter. 25 x 25 cm square metallic horn flaring out to 100 cm square will also provide a degree ofperformance. A .5 mfd special low inductance capacitor charges up in about 60 seconds with the chargershown. Faster charging rates can be obtained by a higher current system available on special request for moreserious research.

A high power radio frequency pulse can be generated where the output of the pulser may also be coupled to afull size center fed 1/2 wave antenna tuned between 1-1.5 MHz. The actual length at 1 MHz is over 150 meters(492 feet) and may be to large for many experiments, however is normalized for an efficiency of 1 with all otherschemes being less. The actual elements may be reduced in length by using tuned 1/4 wave sections consist-ing of 75 meters (246 foot) lengths of wire spaced and wound on 2 to 3 meter pieces of PVC tubing. Thisscheme produces a pulse of low frequency energy

Please note that the pulse output of this system will cause damage to computers and any devices usingmicroprocessors or similar circuitry up to a considerable distance. Always use caution when testing and

using this system as sensitive electronic equipment can be damaged by just being close!!

The following is a description of the strategic parts used in our lab assembled system.

Capacitor ( This part available through our labs)The capacitor ( C ) used for this type of application must have very low inherent inductance and dischargeresistance. At the same time the part must have the energy storage sufficient to produce the necessary highpowered pulse at the target frequency. Unfortunately these two requirements do not go hand and hand. Higherenergy capacitors always will have more inductance than lower energy units. Another important point is the useof relatively high discharge voltages ( V ) to generate high discharge currents. These values are required toovercome the inherent complex loss impedances of the series inductance and resistance of the discharge path.The capacitor used in our system is .5 mfd at 50,000 volts with a .03 uh series inductance. Our target funda-mental frequency for the lower power non disruptive circuit is 1 mhz. The system energy is 400 Joules asdetermined by E=1/2 CV2.. with E at 40 kv.The terminals of the capacitor are brass blocks intended to keep al impedances as low as possible.

Inductor (Easily made by the experimenter for low frequency radio pulse)The inductance shown as ( L1 ) is a lumping of all stray connecting leads, spark switch, exploding wire dis-rupter and the inherent inductance of the capacitor. This inductance resonates at a wide band of frequenciesand must be able to handle the high discharge current pulse ( I ) . The value of the lumped value is around .05uh. .1 uh. The conductor sizes must take into effect the high pulse current ideally equal to V X (C/L) 1/2 . Thisfast current transition wants to flow on the conductor surface due to the high frequency skin effect.You may use an inductor of several turns for experimenting at the lower frequencies along with a coupledantenna .Dimension are determined by the air inductance formula: L= (10 x D2 x N2 )/l where D is diameter incm, l is length in cm, N is turns. A coil from 3 turns of 10 mm (.375”) copper tubing on a 7.5 cm (3”) diameterspread out to 15 cm ( 6”). Calculated inductance is close to .3 uh.

Spark Switch Ref fig 3The spark gap switches the energy from the capacitor into the inductor where a resonant tank is momentarilyset up. The current rise time occurs over the period pi/2 * (LC).5 The gap separation distance is set to fire at thedesired breakdown voltage. The impedance of the spark switch is determined by the equation: ZSP= (k x l)/Qwhere k=.8 x 10-3 , l = spark gap distance in cm and Q = amp-sec of discharge. The gap is self firing andrequires no external triggering. The gap assembly is an intergral part of the discharge path and must be con-structed to minimize inductance and resistance. Fabrication of our lab test unit is shown and is our approach.You may deviate with your own ideas but the objective must be minimal circuit impedance.

You will note that the bottom ball of the spark gap switch is at a high potential and is made adjustable by athreaded rod and locking jam nut scheme. The top ball also uses a threaded rod that fits into the 3/4” PVCtubing used for structural support of the wire disruption scheme.

Low inductance extension pieces are shown used to lengthen the capacitor terminals and are fabbed from 1/4”brass plates with mating holes to the existing block terminals of the capacitor.. The edges are rounded andsmoothed to prevent corona.

Exploding Wire Disruption Switch (High power high frequency pulse)

This is where the stored energy in the circuit inductance is released as an explosion of electromagnetic energyof broadband proportions. The released energy is a function of LI^2 where I is the current rise in the spark gapswitch at the moment the wire explodes. The actual power lost in the spark switch is but a fraction of thatemitted in the explosion of the wire. Selection of the wire size must take into consideration electrical circuitparameters for proper timing for optimum release of energy. We experimented with .1 (4mils) to .3 mm (12 mils)brass wire about 50 cm in length. The wire is attached by a sandwiching action between two flat brass washesas shown. Note that a longer wire will tend to produce more of a magnetic pulse while a shorter will producemore of an electric.

RFC1 Radio Frequency Choke

This component is necessary to keep the fast current pulse rise isolated from the charger multiplier diodes thatcould be avalanched by the rapid dv/dt. Suggested value is around 2 mh with 3 and .3 uh tertiary coils. Theassembly can be solenoidal close wound for the 2 mh section. Space wind 10 turns for 1” for the 3 uh sectionand finally 3 turns spaced over 1” for the .3 uh section. Use #28 magnet wire on a 1 1/2 “x 12” PVC plastictube.

R1 Resistor

Intended as a safety providing a high back impedance should a short occur in the output stage of the currentdriver. Use approximately 50 to 100 k at least 100 watts

Charger

The charger for the system can be any current limited source with an open circuit voltage in excess of 50 kv. Thecharging current rate will determine the amount of time necessary to reach a firing level and need not be that fast forthis experimental system as shown. A single charging cycle produces approx 500 Joules per shot and requiresreloading of the wire for exploding disrupter switch. A 2 ma current source will charge the ..5 mfd capacitor to 50 kv inapprox 5 seconds. This is shown mathematically by t = c v /i (.5)(10e-6)(5*10e3)/.002. This rate is more than ampleand there is no advantage to a higher current system unless you are planning to do a multiple discharge system usinga spark gap driven radiator or wire dispensing scheme.

Our HVOLT10 is an excellent candidate for this section and provides up to 80 kv at 200 microamps.Our 50KVCC10 is shown as plans in this literature and provides an adjustable 10 to 50 kv at up to 500 microamps.Both are available completely assembled and ready to use and are shown on front cover page..

Assembly

Our lab pulser is shown constructed using hardware store available materials and parts. The structure uses acombination of 3/4” schedule 40 PVC tubing for the pillars and flat faced end caps for the retainers. Partitionsare made from non conductive material of structural integrity for the application . We used 3/8” clear acrylicplate stock. Fig 2 inse shows the scheme we used to attach these sections to the flat faced end caps. Thesections are secured by drilling clearance holes and using plastic tye wraps to keep together. Use of PVCcement is obviously stronger but prevents disassembly without destroying the support structure.The pillar and cap assemblies are attached to the partition plates using 1” x 1/4-20 bolts and nuts. The capaci-tor (C1) is secured to the bottom partition by a cradle assembly fabbed from wood or plastic pieces. Thisscheme stabilizes the bottom of the capacitor.The terminal connections of the capacitor are extended by metal plate sections fabbed as shown. These nowattach to the terminals connecting to the exploding wire cavity section via brass threaded rods sleeved intopieces of 3/4” PVC pillar tubing.The bottom spark gap electrode is made adjustable by adjustment of the bottom nut on the extended rod.You will note the 4 longer pillars are positioned at the corners of the bottom and middle partition plates. Theshorter pillars are positioned at the mid sections of the middle and top partition plates. This layout is shown infig 4 top view of middle partition plate.

Application

This system in intended for research into the susceptibility of sensitive electronic equipment to E.M.P. (Electro-magnetic pulse) The system can be scaled down for portable field use operating on rechargeable batteries. Itcan be scaled up to produce kilojoule pulses at the users own risk. No attempt to construct or use this deviceshould be considered unless thoroughly experienced in the use high pulse energy systems

The electromagnetic energy pulse can be focused or made parallel by use of a parabolic reflector. Experimentaltargets can be any sensitive electronic equipment or even a gas discharge lamp.

The acoustical spark energy can produce a sonic shock wave of high sound pressure at the focal length of theparabolic antenna.

Basic TheoryA resonant LCR circuit consisting of components as in the above figure. Capacitor C1 is charged up from constantcurrent charger at Ic. The voltage V across C1 is now related to V = It/C. The spark switch (GAP) is set to fire justbefore V reaches 100,000 volts. Once fired, a peak current rise of di/dt=V/L occurs. The period of circuit response isfunctional of .16 x (LC)^.5. The capacitor now discharges into the circuit inductance in 1/4t with the peak current nowcausing the wire to explode and interrupting this current just before it peaks. The inductive energy (LI^2) is released inan explosive burst of broad band electromagnetic radiation. The peak power is derived via the following and is inexcess of many megawatts!!!!!

1. Charging Cycle: dv=Idt/C (Expresses the voltage charging on the capacitor as a f(t) with I constant current.

2. Storage energy in C as a f(v): E=.5Cv^2 (Expresses energy in JOULES as the voltage increases)

3. Response time 1/4 cycle current peak: 1.57(LC)^.5 (Expresses the time for the first resonant current peakingwhen the spark switch fires)

4. Peak current in 1/4 cycle: V (C/L)^.5 (Expresses the peak current)

5. Initial response as a (f)t: Ldi/dt+iR+1/C+1/Cint idt = 0 {Expresses voltages as a f(t)}

6. Energy JOULES in inductor: E= .5Li^2

7. Response when circuit is disrupted at max current through L: Ld^2i/dt^2 + Rdi/dt + it/C = dv/dt. One now sees the explosive effects of the first term of this simple equation as the energy in the inductor must go somewhere in a very short time resulting in an explosive E X B field energy release

An appreciable pulse of many megawatts in the upper RF energy spectrum can be obtained by destabilizing the LCRcircuit as shown above. The only limiting factor is the intrinsic real resistance that is always present in severalforms.such as leads, skin effect, dielectric and switching losses etc. These losses must be minimized for optimumresults. The RF output can be coupled to a parabolic microwave dish or tuned horn. The Q of the output will dependto an extent on the geometry of the wire switch. Longer lengths will produce more "B" field characteristics while shortmore "E" field. These parameters will enter into the coupling equations regarding the radiation efficiency of theantenna. Experimenting is the best approach using your math skills only for approximating key parameters. Damageto circuitry usuallly is the result of very high di/dt (B field) pulse properties. This is point of discussion!!
