KALI (electron accelerator)

Last updated

The KALI (Kilo Ampere Linear Injector) is a linear electron accelerator being developed in India by Defence Research and Development Organisation (DRDO) and Bhabha Atomic Research Centre (BARC). It is rumoured to have directed-energy weapon capabilities.

Overview

The KALI is a particle accelerator. It emits powerful pulses of electrons. Other components in the machine down the line convert the electron energy into EM radiation, which can be adjusted to x-ray or microwave frequencies. [1]

This has fueled rumours that the KALI could, one day be used in a high-power microwave gun, which could destroy incoming missiles and aircraft through soft-kill (destroying the electronic circuitry on the missile).

History

The project was first founded by Dr. P.H. Ron, and mooted in 1985 by the then Director of the BARC, Dr. R. Chidambaram. Work on the project began in 1989, being developed by the Accelerators & Pulse Power Division of the BARC. DRDO is also involved with this project. It was initially developed for industrial applications, although defence applications became clearer later. [2]

The first accelerators had an electron beam power of ~0.4GW, which increased as later versions were developed. These were the KALI 80, KALI 200, KALI 1000, and the KALI 5000. [1]

The KALI-5000 was commissioned for use in late 2004. [3]

Applications

The KALI has been put to various uses by the DRDO.

The X-rays emitted are being used in Ballistics research as an illuminator for ultrahigh speed photography by the Terminal Ballistics Research Institute (TBRL) in Chandigarh. The Microwave emissions are used for EM Research.

The microwave-producing version of KALI has also been used by the DRDO scientists for testing the vulnerability of the electronic systems of the Light Combat Aircraft (LCA), which was then under development.

It has also helped in designing electrostatic shields to "harden" the LCA and missiles from microwave attack by the enemy as well as protecting satellites against deadly Electromagnetic Impulses (EMI) generated by nuclear weapons and other cosmic disturbances, which "fry" and destroy electronic circuits. Electronic components currently used in missiles can withstand fields of approximately 300 V/cm, while the fields in case of an EMI attack can reach thousands of V/cm.

A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon, which directs focused energy toward a target using atomic scale particles. Some particle-beam weapons have potential practical applications, e.g. as an antiballistic missile defense or detection system. They have been known by several names: particle accelerator guns, ion cannons, proton beams, lightning rays, rayguns, etc.
