Abstract

The design of the solenoidal magnet developed by INFN Sezione di Genova, for the PANDA detector at FAIR (GSI, Darmstadt) is presented here. This is a thin, superconducting coil made using Rutherford-type, aluminum stabilized cable, indirectly cooled using circulation of two-phase helium in a network of pipes welded on an external coil former. The concept of this magnet is the same of many detector magnets, such as BaBar, Finuda, Delphi, CMS and many others: we took them as a guideline, keeping all the critical parameters under the values obtained in working magnets. The way the magnetic (2 T central field, plusmn 2% uniformity, small radial field), thermal (1.8 K safety margin, safe quench behavior) and mechanical ( ~ 100 t magnetic force compensation, path load for nested detectors) requirements were fulfilled is shown here.
