Abstract

Chapter one introduction into plasma physic to know what is
plasma and the model of plasma, also know the meaning of plasma
expansion in plasma general before respect it in white dwarf and
nano-technology then in the last we mention the self -similar
expansion and why use it.
Chapter two we will know what the meaning of white dwarf and
Using self-similar transformation, the basic set of nonlinear
equations is solved numerically. Typical values of white dwarf stars
are used to estimate the behavior of the ion number density and ion
fluid velocity
chapter three the development of accelerators technology offers a
new window for the creation of surface nano-structures in an
efficient and accurate way. The use of 30 MeV C60cluster ions
enables the creation of nano-hillocks of size larger than the ones
produced by GeV monoatomic ions. The physical mechanism
underlying the realization of such nanostructures is elucidated using
a plasma expansion approach. Numerical analysis showed that
increasing the ionic temperature (number density) ratios would lead
to decrease (increase) the nano-hillocks height.
