Current leads in superconducting magnets are widely adopted for heavy current transmission, and HTS DC cables have great advantages when used as current leads for such purposes. However, as an important parameter of HTS DC cables, AC loss has a strong impact on the stability and operation cost of current leads. In this paper, experiments were conducted to measure AC ripple losses of HTS tapes and HTS cables, and simulations of HTS tapes were carried out. The paper has reached conclusions on the relation between AC losses and power frequencies.

Abstract In superconducting magnets, soldering splices are used to connect superconducting cables for providing electrical current paths. One of the main considerations in the splice design is the splice electrical resistance across the joint. High joint resistance can increase the Joule heat generation and thus result in conductor instability. A finite element analysis has been performed to determine the key parameters affecting soldering splice resistance for superconductors with high purity aluminum stabilizers. The parameters investigated include: high purity aluminum RRR value, copper RRR value, solder layer thickness, magnetic field, splice configuration, and operating temperature. The results obtained from this work can benefit splice cooling and the design optimization.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.
