26. A Numerical Investigation on AC Losses in one module of the Central Solenoid of the ITER tokamak

23/09/2021, 12:00

The investigation of electromagnetic transients in the superconducting coils of the ITER magnet system is important in order to compute the losses arising during time-varying operating conditions. The challenge of this analysis is related to the high number of degrees of freedom required to discretize large-scale magnets at the level required for AC loss computation. The Central Solenoid (CS)...

29. Design Studies, Magnetic and Structural calculations for a DEMO hybrid CS proposal

23/09/2021, 12:25

The Roadmap to Fusion Electricity draws on innovative experiments pivotal for the accomplishment of the European DEMO, i.e. the demonstration fusion power plant by the EUROfusion Consortium.
At the end of the pre-conceptual design phase, the machine comprises three main magnetic systems: 6 poloidal field (PF) coils, 16 or 18 toroidal field (TF) coils and the central solenoid (CS), primary...

33. Numerical Studies of High Field-Rate Losses in Cable-In-Conduit-Conductors Carrying Transport Current

23/09/2021, 12:50

In large size conductors for the Central Solenoid (CS) and Poloidal Field (PF) coils of tokamaks, the AC losses set the operating limits for the magnets, especially during the plasma start up. In terms of losses, the startup of the plasma current (breakdown) can be particularly challenging, as the flux density rate can reach values as high as 10 T/s. At such high-field rates, the cable is...

38. High-performance multiphysics FEM simulations in the Sparselizard open source library

23/09/2021, 13:15

This talk demonstrates the capabilities of the open source FEM library Sparselizard
(sparselizard.org) through mini-examples focused on the physics of interest for particle
accelerator magnets. The equations and simulations are set up on the 3D geometry of
CERN’s Feather M2 particle accelerator magnet for the following physics:
 DC electric current flow through the magnet conductor
...
