Magnetron Technology

In News

Recently, the Government said that it is supporting indigenous development of high-powered Magnetron technology used mainly for cancer radiation therapy.

What is Magnetron?

The magnetron is a high-powered vacuum tube that works as a self-excited microwave oscillator.
It is a compact and low-cost source of microwave power as compared to other similar microwave tubes.
It works on a principle of crossed-field device, which uses the motion of electrons in perpendicular electric and magnetic fields to generate microwave radiation, used for generating Radio frequency (RF) Power Source in Linear Accelerator for Medical, non-destructive technology (NDT) and other allied applications.
- NDT is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system.

Data and Statistics

Currently, India is the fourth largest medical devices market in Asia, after Japan, China and South Korea and positioned 20th in the global market.
India imports about 86% of its requirement of medical equipment and almost 100% of high-end medical equipment.
With respect to Magnetron, India would be the third country to achieve this feat. England and Japan hold around 80% – 90 % of the global market.
