The ion-optical scheme construction
method, algorithm and program based on a global and a set of local
co-ordinates choice were developed. The ion-optical scheme of a gas-filled
separator includes dipole and quadrupole magnets, apertures and drift spaces.
The method applied allows trajectory equations to be invariant in different
scheme elements.
