A SEMINAR PRESENTATION ON ELECTRONICS BOMB Presented By: Gopal Dhaker 8th Sem, 4th year
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
History First observed during the early testing of high altitude airburst nuclear weapons. Then FCG is built and tested in US, and then in USSR And more recently in CIS.
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 of volts. its effects on the circuitry of other semiconductor electronics equipments (i.e. MOS). Due to over power the device damages. All types of receivers and communication equipments are highly vulnerable.
Concept of EMP It is an electromagnetic pulse. Produces a powerful electromagnetic fields (i.e. in kilovolts). Due to powerful fields it cause wide damage of electronics appliances. The EMP is in effect an electromagnetic shock wave.
Technology based for E-bomb It is based on Explosively Pumped Flux Compression Generator.
Introduction to Flux Compression Generator It is a type of generator for producing EMP. It is the most mature technology applicable to bomb. FCG is a device capable of producing electrical energies of about tens of Mega joules in ten to hundreds of microseconds. It has peak power kevels of the order of Terawatts to tens of Terawatts.
Working of FCG Producing a pulse of electric current of order of ten of kilo Amperes 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 this operation. So in this method using a fast explosive into the magnetic field.
Targeting E-Bomb The task of identifying targets for attack with E- Bomb is complex. Targets which can be readily identified through conventional photographic, satellite, image radar and human operation. These targets are typically geographically fixed and thus may de attacked providing that aircraft can penetrate to weapon release range. For accuracy GPS/initially guided weapons can be used.
Advantages of E-bomb Permanent damages the electrical appliances such 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.
Limitation It must be noted that thermionic technology i.e. vacuumed tube equipment is substantially more resilient to the electromagnetic weapons. So no damages to the thermionic technology devices.
