Question

what is plasma technologies? how plasma is used in different technologies and also describe its future aspects?

Answer 1

Plasma technologies is an industry that exploits plasma in its processes. For example, being a very hot partly or completely ionized gas plasma is used in welding, metal cutting, plasma spectroscopy, old TVs and oscilloscopes in cathode-ray tubes, and even ordinary circuit breakers in your home, but here it is kind of a side effect. Also, plasma is widely used as a source of light if fluorescent and gas-discharge lamps.

The future aspects of the applications of plasma is to use it in nuclear fusion reactors in tokamaks. A strong magnetic field will hold plasma within a toroidal chamber:

This future technology will be very energy-efficient.
