Abstract

An essential part of the DiMuon Arm Spectrometer of the ALICE experiment is a conventional Dipole Magnet (DM) of about 890 tons, which provides the bending power to measure the momenta of muons. The JINR engineering design of the DM, technical characteristics and description of the proposed manufacturing procedure are presented. The proposed coil fabrication technique is based on winding of flat pancakes, which are subsequently bent on cylindrical mandrels. The pancakes are then stacked and cured with prepreg insulation. The method is demonstrated on hand of the prototype II, which consists of a pancake made with full-size aluminum conductor. Some details of electromagnetic and mechanical calculations are described. The results of measuring of mechanical and electrical characteristics of materials related to the coil composite structure are discussed.
