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.

We are developing magnets with High Temperature Superconducting (HTS) wire. A scanning magnet was designed, fabricated, and tested for its suitability as beam scanner. After successful cooling tests, the magnet performance was studied using DC and AC currents. In AC mode, the magnet was operated at frequencies of 30-59 Hz and a temperature of 77 K as well as 10-20 Hz and 20 K. The power loss dissipated in the coils was measured and compared with the model calculations. The observed loss per cycle was independent of the frequency and the scaling law of the excitation current was consistent with theoretical predictions for hysteretic losses in HTS wires. A 3 T dipole maget is under fablication now.
