During ITER plasma operation, large thermal loads are generated in the stainless steel Toroidal Field (TF) coil casing. To avoid the increase of the TF conductor temperature in Cable in Conducts (CICC), cooling channels are implemented in between conductors and casings inner side, in particular in the plasma facing wall where the most stringent operating conditions in term of magnetic field,...

Tokamak-type nuclear fusion reactors like ITER, under construction in France, use superconducting (SC) magnets cooled by supercritical helium (SHe) to confine the plasma. The small temperature margin available between operation and quench of the magnet requires a careful design of the magnet operating scenarios to guarantee adequate cooling in all phases. Sophisticated thermal-fluid dynamic...

The two cyclotron gas stopper superconducting solenoid coils were designed to be cooled down and to be kept cold in the range 4.25 K to 4.6 K using three pulse tube coolers per coil. These coolers are designed to produce from 1.4 to 1.7 W per cooler when the cooler first stage is at about 40 K. The cyclotron gas stopper coils are designed that they can be separated while cold, but unpowered....

Superconducting coils in AC application have losses which tend to warm up the coil and so limit the performance. Good thermal contact between the coil and the cooling agent is very important. Cooling by heat conduction is no option since big metallic plates in close contact with the coil generate eddy-current heating. In this research we investigate the possibility of cooling the coil with by...

The superconducting solenoid of the PANDA experiment at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, is designed to provide a magnetic field of 2 T over a length of about 4 m in a bore of 1.9 m. To allow a warm target feed pipe oriented transversely to the solenoid axis and penetrating through the cryostat and solenoid, the magnet is split into 3 inter-connected...

The Mu2e Transport Solenoid (TS) consists of two separate but similar solenoids, TS-u and TS-d. Each solenoid is in the shape of a quadrant with a centerline radius of approximately 3 m and has a helium cooling loop consisting of 25 vertically oriented rings with diameters ranging from 1 m to 1.25 m connected in series. This cooling loop configuration has been deemed adequate for cooling via...
