  A heavy-ion accelerator facility based on linear accelerator is planned in Korea. The facility is designed to provide high-current radioisotope beams with various users. The primary beam energy is in the range of a few hundreds of MeV/u. The major mechanism to produce isotope beams is in-flight fragment separation. The rare isotope beams are to be utilized in the fields of nuclear, material and biomedical sciences. The separator system should have high mass resolution to identify and separate rare isotopes of interest, and also large momentum and angular acceptances for maximal utilization of produced isotopes. We are considering improved beam optics design to realize such a system, where all second order aberrations are corrected. The study has been performed mainly using COSY Infinity, and the results will be presented.

  Magnetic cylindrical lens is used mostly in beam lines to focus and transport low energy beam. It is well known that focusing power of a magnetic solenoid lens depends on the ratio of particle momentum and electric charge. A solenoid rotates also an ion beam while focusing it and the phase space areas of the beam in x- and y-plane get entangled and increased. The paper reported here describes an effort to design a new magnetic Einzel lens using a pair of Glaser lens in anti-solenoid mode for the first time to get zero rotation of the exit beam. Analytical formulae have been generated to deduce the scalar magnetic potential and field along the central axis of the lens. Thereafter, beam optics and particle tracking is done using the combined field of a pair of Glaser Lenses constituting the magnetic Einzel lens. The required focusing power of the designed lens is achieved for a beam of given rigidity.

  All the major components of the extraction system of the Kolkata superconducting cyclotron are installed and functional. It includes the Electrostatic deflectors, magnetic channels, M9 slit etc. Internal beam acceleration has already been done successfully and now we are on the verge of extracting and transporting the beam to the cave. The external beam transport system has been designed comprising of quadrupole magnets, steering magnets, switching magnets, beam diagnostics etc. One of the four beam lines has been installed, which extends 20 meters up to the experimental cave - 1. Control and monitoring system for all these components have been developed and tested. All the beam dynamical and technical aspects of the beam extraction and beam transportation have been discussed in this paper.
