GSI, Darmstadt, is planning to build FAIR (Facility for Antiproton and Ion Research). This facility will include the SIS300 stage, a fast-ramping heavy ion synchrotron with a rigidity of 300 T-m, based on 6-T, 100-mm coil aperture superconducting dipoles, ramped at 1 T/s. This article presents investigations concerned with development of the SC dipole for the SIS 300 accelerator. Measured characteristics of the most suitable steels for the iron yoke as well as of superconducting cable are presented. The results of a study of experimental and calculated differences between straight and bent dipole coils are shown. Optimization of geometries from the viewpoint of magnetic and mechanical characteristics was carried out.

The cryogenic and vacuum system is built to cool by superfluid helium at 1.8 K two niobium cavities of the RF superconducting kaon separator being under construction at IHEP. First commissioning runs were carried out. During the last run both cavities were successfully cooled down to the operating temperature and cryostated for several days. System description, test results and planned improvements are presented.
