Numerical simulation of ion motion in gas-filled magnetic mass-separators

In the paper parameterizations of the main processes of ion-molecular interactions in gas-filled magnetic mass separators are presented. Using theses parameterizations, two programs for computer modeling of ion motion in gas-filled separators are developed: one utilizing the transfer matrix method in paraxial approximation and the other one based on the program SIMION 7.0. Examples of test calculations of focusing of products of nuclear fusion reactions in the separator DGFRS of the Laboratory of nuclear reactions in JINR, Dubna, are given.
