About
Thermal and non-thermal plasmas are gaining immense importance in recent time due to its wide spread use in numerous industrial applications. While the fundamental physics remains the same, newer plasma devices and novel plasma generation techniques are becoming more and more important to meet the stringent requirements of the challenging application areas. The course offers an in-depth understanding of the device physics, process chemistry and plasma diagnosis that forms a key factor in any successful development. With a crisp theoretical understanding at the beginning, the course deals with device physics and process chemistries in plasma at length. Together with a detail understanding of the plasma generation and thermo-physical properties, most of the important diagnostic techniques of industrial plasmas are covered next. The course ends with a comprehensive understanding of some of the advanced technological applications in recent time.
Intended audience: M.Sc., Ph. D. and Post Doctoral Students and Researchers, Hospital Doctors and Staff and Industry People and Defence Personnel
Prerequisites: B.Sc in Physics or B.E/B. Tech in Mechanical/Electrical/Chemical Engineering, The course is a stand-alone course for a thorough understanding of different types of industrial processing plasmas and their wide range of interesting applications.
