Design study of the KINRIS isotope separator with a 270° wide aperture magnet

A new isotope separator KINRIS (Kiev Institute for Nuclear Research Isotope Separator) is being constructed at the Institute for Nuclear Research in Kiev (Ukraine). This paper reviews main features of the electromagnetic separator for stable isotopes production using an analyzing magnet with an inhomogeneous magnetic field. Beam-optical principles of the KINRIS separator and results of beam-optical calculations are discussed. In this paper we consider the influence of a beam emittance, momentum spread and aberrations on the mass resolving power of the KINRIS separator. Results show that this separator can be used for isotopes production with an excellent efficiency for any ion mass.
