Heavy ions acceleration in RF wells of 2-frequency electromagnetic field and in the inverted FEL

PDF Version Also Available for Download.

Description

Last results of the study of heavy ions acceleration by electrons trapped in moving 2-frequency 3-D RF wells are described. A linearized theoretical model of ions acceleration in a polarized spheroidal plasmoid is proposed. The equilibrium state of this plasmoid is described by the modified microcanonical distribution of the Courant-Snyder invariant ({open_quotes}quasienergy{close_quotes} of electrons). Some new results of computational simulation of the acceleration process are given. The method of computation takes into account the given cylindrical field E{sub 011}({var_phi},r,z) and the self fields of electrons and ions. The results of the computation at relatively short time intervals confirm the idea ... continued below

Description

Last results of the study of heavy ions acceleration by electrons trapped in moving 2-frequency 3-D RF wells are described. A linearized theoretical model of ions acceleration in a polarized spheroidal plasmoid is proposed. The equilibrium state of this plasmoid is described by the modified microcanonical distribution of the Courant-Snyder invariant ({open_quotes}quasienergy{close_quotes} of electrons). Some new results of computational simulation of the acceleration process are given. The method of computation takes into account the given cylindrical field E{sub 011}({var_phi},r,z) and the self fields of electrons and ions. The results of the computation at relatively short time intervals confirm the idea and estimated parameters of acceleration. The heavy ion accelerator using this principle may be constructed with the use of compact cm band iris-loaded and biperiodical waveguides with double-sided 2-frequency RF feeding. It can accelerate heavy ions with a charge number Z{sub i} from small initial energies {approximately} 50 keV/a.u. with the rate {approximately} Z{sub i} {center_dot} 10 MeV/m. Semirelativistic ions may be accelerated with similar rate also in the inverted FEL.
