Radial evolution of the finite-width plasma sheet in a z-pinch: a parametric analysis based on conservation laws

Summary form only given. A simple method that allows one to estimate the macroscopic variables (width, temperature, density, radial velocity, etc.) of the plasma sheet in the first compression of a z-pinch, is presented. From an analytical study of the formal solution, a well-defined range of validity for each parameter of the model has been found. Based on physical conditions, these ranges of validity give a criterion to understand the necessary conditions to build and maintain a moving plasma sheet. Using this model, other geometries besides the cylindrical one can be analyzed in the future.
