Single Shot Pulsed Gigawatt Electron Accelerators

Multiple Shot, 1 GW, 10 -100 Hz, Linear Induction Accelerator

Development of High Power Pulsed Electron Accelarators 

Single Shot Pulsed Gigawatt Electron Accelerators

Indigenous technology for Electron Accelerator technology development was carried out meticulously and has built four accelerators starting with a modest power level of 0.4 GW, APPD has successfully developed accelerators with a power level of 40 GW. KALI series of accelerators includes KALI 80, KALI 200, KALI 1000, and KALI 5000. 
    
KALI – 5000: This system is designed to produce electron pulses of about 100 ns with an energy of about 1 MeV, current 40 kA and a power of 40 GW. This Relativistic Electron Beams (REB) thus generated will be used for the generation of High Power Microwaves (HPM) & Flash X Rays (FXR). Commissioning trials for KALI 5000 system have begun. 
A view of a 1 MeV, 50 -100 ns, 40 GW pulsed accelerator (KALI 5000) is depicted below

 Multiple Shot, 1 GW, 10 -100 Hz, Linear Induction Accelerator – LINAC                                                                                 

This Accelerator will deliver electron beam at the rate of 10 - 100 Hz with an energy and current of 200 keV, 5kA respectively. The pulse length will be around 50 ns. In this device, double exponential electrical pulses of 20 kV/20ms produced by a solid state driver are amplified, compressed and shaped into rectangular pulses of 75 kV / 50 ns by successive stages of magnetic compression switches. These pulses are fed into a two-stage induction accelerator cavities, for accelerating the electron beams to about 1 GW of power (peak). This accelerator will also be used for generating HPM and FXR and dynamic imaging. Most of its subsystems are in the advanced stage of fabrication.

Pulse Power Systems: 

A technology developed over the last 25 years or so.

80 Joules Pulse Power System
gifted to IIT Chennai

Pulse power system gifted to IIT Chennai: A MARX bank based, 300 kV, 2kA, 100 ns pulse power source was gifted to High Voltage Electrical Engineering deptt. of IIT Chennai.
A view of this source is shown in Figure. It is being used as an educational tool for imparting training and teaching to the B.Tech, M. Tech and Ph.D. students about designing the MARX generator and their characterizations.
