806. Wed-Mo-Or11-01 [Invited]: Magnetization, Flux Penetration, and Drift of YBCO Cable Segments Models and Measurements for Accelerator Magnet Applications

Prof. Mike Sumption (The Ohio State University)

Invited Oral Presentation

High temperature superconductors, such as YBCO, are being considered for high magnetic field magnets to be used in particle accelerators. A knowledge of the magnetic properties of these superconductors, and in particular the cables made from them are needed for accelerator magnet design. Here we present measurements of HTS CORC and Roebel cables using two devices. First, from a hall probe rig...

927. Wed-Mo-Or11-02 [Invited]: Magnetic field measurements of stack of double-pancake coils wound with striated and copper-plated coated conductors

Prof. Naoyuki Amemiya (Kyoto University)

Invited Oral Presentation

Striation is one of the approaches to reduce the shielding-current-induced fields (SCIFs) in magnets wound with coated conductors. We focus striated and copper-plated coated conductors, in which the current sharing between filaments through plated copper could improve their stability and could help their quench protection. It should be noted that the striation is effective to reduce SCIF only...

1518. Wed-Mo-Or11-03: Experimental results of field-error cancellation with HTS-based magnetic screens

Mr Lorenzo Bortot (CERN)

Contributed Oral Presentation

Future circular accelerators for high-energy particle physics are expected to rely on increasingly higher magnetic fields for steering and focusing the particle beams. High temperature superconductors (HTS) are a promising technology for such future accelerator magnets. In particular, superconducting tapes based on rare-earth cuprate compounds (ReBCO) are potentially excellent candidates. Such...

683. Wed-Mo-Or11-04: Magnetic vector potential-based formulations for modeling superconducting applications: a valid alternative to the H-formulation

Francesco Grilli (Karlsruhe Institute of Technology)

Contributed Oral Presentation

In recent years, the H-formulation of Maxwell’s equation has become the de facto standard for simulating the time-dependent electromagnetic behavior of superconducting applications with commercial software. However, there are several situations where the H-formulation is not the most suitable tool. These include for example: i) situations where the superconductor is better described by the...
