The twin-box pancake joints for the PF coils of ITER will be constructed by connecting overlapping sections of the cable-in-conduit conductors with copper soles. For the analysis of the stability of these joints in a plasma scenario, it is necessary to know how its coupling losses respond under different orientations of the background field. For this purpose, a new model has been developed...

Finite-element models are a powerful and widely used tool for evaluating the ac losses of HTS tapes and wires as well as of assemblies such as cables and coils. The H-formulation, which uses the magnetic field components as state variables, has proved to be an efficient implementation to solve 2-D problems, involving infinitely long or axially-symmetric geometries. However, the simulation of...

Many modelling software packages utilise predetermined coordinate systems and readily embedded metric. However, sometimes these coordinate systems are not practical for modelling or they present too restricted view of the real world. Manifolds and differential geometry offer a more general framework for modelling than coordinate systems can do. For computations we always need some charts, i.e....

Today's particle detectors for high-energy physics are >10m in size and have <100 micrometer spatial resolution. This is for the detector elements which measure particle momenta by curvature in magnetic fields. Other detector elements do measurements by absorbing the energy of particles.
Large size paired with fine resolution are due to the very high energy of the elementary particles...
