Effect of static magnetic island on ITG of ADITYA-U tokamak
Vibhor Kumar Singh, Amal R Biju, Jaya Kumar Alageshan +10
Magnetic islands play a crucial role in regulating plasma confinement in tokamaks by interacting with micro-instabilities, such as the ion temperature gradient (ITG) mode. This wor…
Multiphysics Simulation and First Prototype Development of a Microwave Plasma System for Chemical Vapour Deposition (CVD) Applications
Akash Akash, Sanjeev Kumar Pandey, Venkata Sai Teja Madana +9
With the aid of COMSOL multiphysics simulations, a compact microwave plasma reactor operated at 2.45 GHz frequency has been designed for diamond film deposition. The reactor consis…
