“…The TF coil manufacturing is described in [9][10][11][12]. The major technical challenges of TF coil manufacturing were (1) wind, react and transfer technology to insert the conductor into the RP [10,12,13], (2) development of electrical insulating performance with high radiation condition [10,14], (3) accuracy of the CCL positioning to minimize the error magnetic field [9,10,15,16], (4) welding and machining technology within severe tolerances for the huge structures [9,11,[15][16][17][18].…”

“…The future updating of large-scale superconducting magnets for high-energy applications, such as those involved in the High-Luminosity Large Hadron Collider (HL-LHC) project [1], and fusion energy projects such as ITER [2], both require the optimal designing of high current capacity cables for minimizing the number of Ampere-turns in the manufacturing of superconducting coils. Thus, in the last few years a very promising design of high temperature superconducting cables has started to dominate the landscape for high field applications [3] by following the simple concept of winding Coated Conductors On a Round Core, nowadays known as CORC ® cable [4].…”

Conductor on a rounded core (CORC ® ) cables with current densities beyond 300 A/mm −2 at 4.2 K, and a capacity to retain around 90 % of critical current after bending to a diameter of 3.5 cm, make them a strong candidate for high field power applications and magnets. In this paper, we present a full 3D-FEM model based upon the so-called H-formulation for commercial CORC ® cables manufactured by Advanced Conductor Technologies LLC. The model presented consists of tapes ranging from 1 up to 3 SuperPower 4mm-width tapes in 1 single layer and at multiple pitch angles. By varying the twist pitch, local electromagnetic characteristics such as the current density distribution along the length and width are visualized. Measurements of macroscopical quantities such as AC-losses are disclosed in comparison with available experimental measurements. We particularly focused on the influence of the twist pitch by comparing the efficiency and performance of multiple cables, critically assessing the optimal twist pitch angle.
