Interaction between two seed plasma plumes and subsequently formed interaction zone have
been investigated in vacuum and wide range of ambient conditions. Different combination of
solid targets, e.g. carbon, aluminium, nickel, tungsten etc. have been used in present study. The
time resolved fast imaging and optical time-of-flight techniques have been utilised to inves-
tigate the formation, dynamical and spectral behaviour of the seed plasma plumes as well as
interaction zone. Also optical time-of-flight technique has been employed to observe the veloc-
ity distribution of both the ionic and neutral particles in both the regions. The key features, such
as shape, size and dynamics of the primary plume as well as resultant interaction zone have been
examined. Observed dynamical and geometrical features of the interaction zone are explained
on the basis of plasma parameters and kinetic energy imbalance of the interacting seed plumes.
This experimental findings have important roles in generation of multi-species plasma plume
and to control their contribution in different applications.
