Development of 10 T dipole magnets for the Large Hadron Collider

Development of high field dipole model magnets for future high energy accelerators has been carried out as a part of the cooperative accelerator program between CERN and KEK. A single aperture dipole model magnet was completed and tested. The magnet reached 8.0 T at 4.3 K and 9.87 T at 1.8 K. A twin aperture dipole model magnet with an identical coil design is being assembled. The development status and test results are described.<>
