Beam Injection into the Nuclotron

The system for the single-turn injection of 5 MeV/u heavy ions into the Nuclotron is described. The system comprises a superconducting septum-magnet, kick electric plates, beam diagnostic apparatus and magnet correctors. The septum magnet has an iron yoke. The coil and septum made of a hollow superconductor, are cooled with a two-phase helium flow. The magnetic field is 1T. The electric field and its fall time in the fast kicker are 7 kV/cm and about 100 nsec, respectively. The beam diagnostics are composed of the Faraday cups and multi-wire collector chambers for current and profile measurements over a wide range of intensities. The magnetic correctors in the beam line and the Nuclotron ring are used for injection adjustment. The system has operated since 1992. The experimental results are presented.
