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
Rajagopala Chidambaram (born 11 November 1936) is an Indian Physicist who is known for his integral role in India's nuclear weapons program; he coordinated test preparation for the Pokhran-I (1975) and Pokhran-II (1998).

. 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.
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.
The KALI-1000 was commissioned for use in late 2004.

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.
