Abstract
The optimization of separator masses in this paper is based on the realization of the linearity of the system under study and the consequences of Liouville’s theorem. The properties of several mass separators with an ion energy of 30 keV and a beam emittance of 4 mm mrad are considered. Focusing is provided by an aberration-free lens and a magnetic corrector. Phase diagrams along the beam path are in the form of parallelograms, which indicates the absence of geometric aberrations. For each of the separators, the resolution calculated in the linear approximation coincides with the simulation results. It is shown that a mass separator based on a magnet with a rotation angle of 54.7° has a resolution of about 5000, and a separator based on two magnets with a rotation angle of 45° and 90°, respectively, has a resolution of 14 000–15 000.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
