1. Regular Production of Hydrogen and Argon Plasmas.
Regular Coating of graphite samples under different RF plasma conditions (Gas pressure, RF power and for different durations to obtain best possible parameters for coating)
Characterization of presence of tungsten in the coated Samples have been carried out. Adhesion testing also been carried out. Thickness test has been carried out.
Significant Amount of spectroscopic data has been recorded. Vibrational temperature has been estimated using vibrational bands.
Graphite limiter tile of ADITYA-U tokamak has been successfully coated with tungsten and handed over to tokamak division for insertion into the machine and will be inserted in plasma soon
Analysis of data from earlier coating experiments to estimate the electron temperatures and gas temperatures.
