Abstract
A large Dipole Magnet is required for the Muon hrm spectrometer of the ALIC E experiment in the future LHC. The absence of constraints of symmetry and homogeneity of the magnetic field has lead to a design dominated by economi cal and feasibility considerations. In March 1997 the decision was taken to build a resistive dipole magnet for the muon spectrometer of the ALICE experiment. Since then design work has been pursued in JINR/Russia and at CERN, While a common concept has been ad opted for the construction of the steel core, two different proposals have been made for the manufacturing technology of the excitation coils. In both cases, however, the conductor material will be Aluminum, The general conce pt of the dipole magnet is based on a window frame return yoke, fabricated from low carbon steel sheets. The flat vertical poles follow the defined ac ceptance angle of 9 degree, The excitation coils are of saddle type. The co ils are wound from large hollow Aluminum profiles. They are cooled by press urized demineralized water. The coil ends are located to both sides of the magnet yoke and determine the overall length of the magnet. The main flux d irection in the gap is horizontal and perpendicular to the LHC beam axis. Both coil concepts and the underlying manufacturing technology are compared and the present status of the development of the magnet is described.
