Enhanced Beam of Protons in Plasma Gas for Three Systems (Tokamak, Z-Pinch and ICF)

Full Text PDF

Abstract:

The interaction of fast beam of proton impinging on a plasma target is treated theoretically, since in general the number density of the beam ions nb is much smaller than the electron density ne of the plasma target. The interaction between proton clusters (collective and individual) with plasma gas is evaluated using the dielectric dispersion function Vlasove formalism both for single and correlated protons.In present work interaction clusters for proton on three different systems (tokamak, Z-pinch and inertial confinement fusion (ICF)) were used at different thermal energy (1000, 20 and 300) (a.u) and densities of proton (1013, 1018 and 3x1022) cm-3 at three velocities (1,7.5 and 35) a.u. to study the effect of these parameters. Found that collective excitations give a small contribution to the energy loss of single ions, We obtain the best beams of the protons in the system (ICF) and at high rates (0,0.2,0.4,0.6) increase with increasing density. This gives a good beam of plasma proton use in different applications such as metal alloying, surface treatment, implantation, surface analysis, sputtering, determination of geometrical structures of polyatomic ions in addition give information about a variety of atomic-collision phenomena.
