1. A SEMINAR PRESENTATION ONELECTRONICS BOMB Presented By: Gopal Dhaker8th Sem, 4th year

2. INTRODUCTION- E-Bombs are weapons of electrical mass destruction- Can damage wide range of electrical & electronics equipments i.e.computers, radios, radar, wires or PCBs etc.-they use of non-nuclear confrontation.- using principle of EMP effect.- It has combination of both electric and magnetic fields.- emp device can render the electronics equipments 3. History First observed during the early testing of highaltitude airburst nuclear weapons. Then FCG is built and tested in US, and then inUSSR And more recently in CIS. 4. BASIC PRINCIPLE Work on principle of EMP method EMP stands for: Electromagnetic Pulses. They very strong pulses. They has short lived transient voltages of thousands ofvolts. its effects on the circuitry of other semiconductorelectronics equipments (i.e. MOS). Due to over power the device damages. All types of receivers and communication equipmentsare highly vulnerable. 5. Concept of EMP It is an electromagnetic pulse. Produces a powerful electromagnetic fields(i.e. in kilovolts). Due to powerful fields it cause wide damageof electronics appliances. The EMP is in effect an electromagnetic shockwave. 6. Technology based for E-bomb It is based on Explosively Pumped FluxCompression Generator. 7. Introduction to Flux Compression Generator It is a type of generator for producing EMP. It is the most mature technology applicable tobomb. FCG is a device capable of producing electricalenergies of about tens of Mega joules in ten tohundreds of microseconds. It has peak power kevels of the order ofTerawatts to tens of Terawatts. 8. Working of FCG Producing a pulse of electric current of order of ten of kiloAmperes to Mega Amperes. It has cylindrical copper tubes of armature. This tube is filled with a fast high energy explosive. Armature is surrounded by a helical coil of heavy wire. Which forms the FCG stator. The start current is supplied by an external current source.Such as a high voltage capacitor bank. So by this a intense magnetic field is produced during thisoperation. So in this method using a fast explosive into the magneticfield. 9. Figure explanation 10. E-bomb warhead 11. Targeting E-Bomb The task of identifying targets for attack with E-Bomb is complex. Targets which can be readily identified throughconventional photographic, satellite, image radarand human operation. These targets are typically geographically fixedand thus may de attacked providing that aircraftcan penetrate to weapon release range. For accuracy GPS/initially guided weapons can beused. 12. Lethal footprint of a E-Bomb 13. GPS guided bomb 14. Advantages of E-bomb Permanent damages the electrical appliancessuch as computers and micro processor devices. Easy to diffuse or to destroy the missiles. Destroys the communication system. It can even stop working of generator or cars. Easy to handle and target. 15. Limitation It must be noted that thermionic technologyi.e. vacuumed tube equipment is substantiallymore resilient to the electromagnetic weapons. So no damages to the thermionic technologydevices. 16.
