Abstract :
KEK has been conducting the design study of the beam separation dipole magnet, D1, for the High Luminosity LHC (HL-LHC) upgrade within a framework of the CERN-KEK collaboration. The D1 magnet has a coil aperture of 150 mm using Nb-Ti superconducting cable and the nominal dipole field of 5.6 T can be generated at 12 kA and 1.9 K. A field integral of 35 T·m is required. The development of the 2-m-long model magnet has been started since May 2013. This paper describes the development status of the short model magnet as well as advancement of the fundamental design studies.
