The ITER Poloidal Field (PF) magnet system consists of six coils. Niobium-Titanium (NbTi) is used as superconducting material and cable-in-conduit conductor(CICC) type are used as a conductor. All coils are fabricated by stacking 6 to 9 double-pancakes wound by two-in-hand winding scheme. The six PF coils (PF1 to PF6) are attached to the Toroidal Field (TF) coil cases through flexible plates or sliding supports to allow small radial and vertical displacements. The outer diameters of the coils vary between 8 m and 24 m. Since the PF coil system provides magnetic field for plasma shaping and position control together with the Central Solenoid (CS) coil, it needs to operate in fast pulse mode, leading to induced voltages of up to 14 kV on the coil terminals during operation.PF coils will be procured by the European and Russian domestic agencies under separate procurement arrangements (PA). Manufacturing design, equipment installation including design and commissioning, and component qualification are the required first steps before entering series production. This paper presents the updated design for manufacturing of components such as tail, joint, clamp and protection cover. Their fabrication and assembly methods are also described. The paper concludes with a summary states report on component qualification program.

Abszract -The 1.5 Tesla superconducting solenoid is part of the BABAR Detector located in the PEP-I1 BFactory machine at the Stanford Linear Accelerator Center. The solenoid has a 2.8 m bore and is 3.7 m long.The two layer solenoid is wound with an aluminum stabilized conductor which is graded axially to produce a +/-3% field uniformity in the tracking region. The 24 month fabrication, 3 month installation and 1 month commissioning of the solenoid were completed on time and budget. This paper summarizes the culmination of a 3 year design, fabrication and testing program of the BABAR superconducting solenoid.The work was completed by an international collaboration between Ansaldo, INFN, LLNL, and SLAC. Critical current measurements of the superconducting strand, cable and conductor, cool-down, operation with the thermo-siphon cooling, fast and slow discharges, and magnetic forces are discussed in detail.

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.
