“…The conductor consists of a superconductor flat Rutherford cable soldered in a high purity copper C-form beam profile 4 mm 7 mm The operational current is 1880 A that is essentially smaller than the current of 5 kA (or higher) in large detector magnets with the same magnetic induction 2 T in the central area [2], [3]. The flat cable is braided of 11 superconducting strands 0.6 mm in diameter which have 54 superconducting filaments of a diameter 54 .…”

“…Thus the requirement of the radiation transparency has not been included in the specification for the materials of the solenoid coil. So, the design can differ from the traditional one for large detector solenoids with an aluminum stabilized superconductor implying an inner winding method [2], [3]. The solenoid is of a split type to ensure a warm hole of 100 mm in diameter between the unequal coil parts for the Cluster Target System mounting.…”

A magnet system comprising a 2 T superconducting solenoid for a target spectrometer and a large aperture dipole magnet for a forward spectrometer is being developed for the PANDA experiment at GSI. The inner radius of the solenoid coil is 1.1 m. The solenoid is of a split type to provide a warm bore between the coil parts for the target. An energy of 23 MJ is stored in the magnet. The Dipole Magnet will provide a bending momentum of 2 T m. The magnet is of the "H-type" with a water-cooled winding. The paper covers magnetic field and forces calculations as well as strength analysis and description of the magnet system components and their implementation.

“…The superconducting compensating solenoid of the ZEUS experiment in the HERA accelerator was designed, built and tested by Ansaldo ABB Componenti under a commissioning of the Italian Institute for Nuclear Physics (INFN) Ill. The principal requirements for this compensating solenoid are: -to reach a field inteeral 10% higher than the ZEUS thin solenoid [ 2,3] with a maximum coil length of 1.2 m and a warm bore of 280 mm in diameter ; -to have a reproducible and well known magnetic axis position; -to have a negligible fringe field. The philosophy adopted in the design was for an epoxy impregnated bath cooled coil with a cold iron yoke, both directly supported by the inner pipe of the helium chamber.…”

A bath cooled superconducting solenoid with a 280 mm in diameter warm bore, a coil length of 1200 mm and a central field of 5 T at the rated current of 950 A, was built at Ansaldo ABB Componenti. It will operate as compensating coil inside the Zeus Detector at HERA, Desy. The coil is shielded by a 3.5 tons low carbon steel cold yoke and the cold helium chamber was designed to withstand a max pressure of 20 bar. The main results obtained during the cool down and energization are reported.
