Ideal focusing systems with homogenous magnetic fields

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2020
Cases of charged particle pack ideal focusing in the presence of constant magnetic field have been considered. One-directional ideal space-time focusing was shown to remain only on conditions that a magnetic field being homogenous and its direction being
