KALI (Kilo Ampere Linear Injector) Electron Accelerator – Complete Details

Indians are familiar with the Goddess “Kali” – the fierce aspect of the goddess Durga. Kali is said to be the Goddess of Time (Creation, Change, Preservation, Destruction) and Empowerment. When it comes to the defense area in India, KALI denotes Kilo Ampere Linear Injector. Discussions about this topic is going on globally.

What is KALI ?

KALI or the Kilo Ampere Linear Injector is the INDIA’s TERMINATOR WEAPON. This linear electron accelerator being developed in India. This weapon made by combined effort from Defence Research Development Organization (DRDO) and the Bhabha Atomic Research Centre (BARC). This is not a laser weapon as most of them think.

People Behind KALI

Director of the BARC, Dr. R. Chidambaram has started the project KALI in in 1985. He was the Scientific adviser to the Prime Minister, and the Chairman of the Atomic Energy Commission.Accelerators & Pulse Power Division of the BARC Began Work on the Project in 1989 in support with DRDO. 

First, Kali developed for industrial application. Defence applications of the device became clearer later. Using a power of ~0.4GW, first accelerators developed. Then later versions were developed like KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000.

How Kali Works?

This is a powerful Electron Accelerator. This works in a way that this particle accelerator emits powerful pulses of electrons. This is a not a laser weapon. Relativistic Electron Beams- REB and other components in the machine , down the line convert the electron energy into EM Radiation.

During operations this can be used for producing  x-ray (as Flash X-Rays) or microwave (High Power Microwave) frequencies. This can be used as a  High-Power Microwave gun and this helps to destroy incoming missiles and aircraft through soft-kill.

So Kali works in a way that, this destroying the electronic circuitry on the missiles. 

Design and Features of Kali

KALI series includes KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000. These are called “Single Shot Pulsed Gigawatt Electron Accelerators”. They are the single shot devices. All these using  water filled capacitors to build the charge energy. 1GW is the range of discharge. They are able to reach 40GW with Pulse time of 60 ns. 

  • Range of Microwave radiations emitted by the KALI-5000 is 3–5 GHz
  • KALI-5000 pulsed accelerator offer 1 MeV electron energy &  50-100 ns pulse time
  • KALI-5000 works with 40kA Current and 40 GW Power level
  • KALI-5000 weighing 10 tons & KALI-10000, weighing 26 tons
  • Require a cooling tank of 12,000 liters of oil


Uses of Kali

  • X-rays emitted are used in Ballistics research as an illuminator for ultrahigh speed photography by the Defence Ballistics Research Institute (DBRL)
  • Microwave emissions are used for EM Research
  • Used by scientists for testing the vulnerability of the electronic systems of the Light Combat Aircraft (LCA)
  • Helped in designing electrostatic shields to “harden” the LCA and missiles from microwave attack by the enemy
  • Protecting satellites against deadly Electromagnetic Impulses (EMI) from nuclear weapons and other cosmic disturbances
  • Kali “fry” and destroy electronic circuits in Enemy weapon


KALI have potential for a military role as a beam weapon. This weaponisation is a threat for many enemy countries. The fact is that,  there is no official confirmation about the system is fully developed or not to use as a weapon. In future this may be used as a  weaponized KALI in an Il-76 aircraft as an airborne defence system or as an anti-satellite weapon or a space-based weapon system.

  1. Kali is one of the best defence machine but due to its requirement and long recharge time its use today is none.
    I am a developer,working on concentration of high power lasers.Lasers can be the best alternative as it needs only electrical energy and can ever pierce hardest armours via melting them.
