In fusion devices, conditioning of vacuum vessel wall is important to get better plasma parameters. The impurities affect the plasma parameters such as density, temperature, and confinement time. Lithium coating on plasma-facing components is one of the techniques for wall conditioning to minimize the impurity level and to improve plasma parameters. In the ADITYA tokamak, we have performed a series of experiments with different types of in situ lithium coating. We observed reduction in the impurity level after lithium coating. This paper presents different types of in situ lithium coating in the ADITYA tokamak and the experimental observations.
