Solenoid Magnet and Flux Return for the PANDA Detector

In this paper we present the project of the Solenoid Magnet for the PANDA detector developed in Genova. This project features a coil realized with a Rutherford--type, aluminum stabilized superconducting cable, wound inside an aluminum alloy coil former and indirectly cooled with a forced circulation of liquid helium. The concept of this magnet is based on many other working magnets, developed for different detectors, such as BaBar, Finuda, Delphi or CMS. A complete characterization of the magnetic, mechanical and thermal properties of the magnet is presented, with an ansatz on the time schedule to be followed to fulfill the detector deadlines.
