Status of the ALICE Magnet System

Alice is the LHC experiment dedicated to heavy ion (Pb, Ca) physics. Alice will be installed in point 2 of LHC, the former point 2 of LEP. The luminosity at the interaction point will be in the order of 10 (10 for p–p). Consequently, the radiation level in Alice will be comparatively low. We will use the existing infrastructure. Therefore, no noticeable civil engineering work will be necessary. Minor modifications will be made to gain a second access to the experiment cavern—mainly for the muon arm spectrometer. ALICE will reuse the L3 solenoid, which is already installed and has been used in LEP as spectrometer magnet. A dipole magnet with a very large aperture is in addition required for the Dimuon Arm spectrometer and will be installed next to the L3 solenoid. The detectors in Alice are concentrated around the IP inside L3 (Barrel) and along the muon arm. Some small forward detectors will be located toward the injection area at a larger distance from IP ( 100 m). After a review of the present status of both projects some important milestones will be highlighted in the conclusion.
