Abstract
In this paper, we report the measurement of ion density, electron density and electron temperature of the plasma blob produced by plasma gun (PG) inside a curved vacuum chamber using cylindrical double probe. The double probe is placed at different distances from the plasma gun and the profiles of ion density, electron density and electron temperature are obtained. The plasma parameters change continuously as the plasma blob propagates away from the source. As the blob moves away from the source, the dynamics of oppositely charged species are different although the resultant effect contributes towards a coherent structure. The profile of electron temperature is fluctuating in nature which may be due to some sort of perturbation phenomena occurring during the motion of the plasma blob.
