The superconducting (SC) magnets used to confine the plasma in nuclear fusion reactors must be first cooled from 300 K down to ~4-5 K, then kept sufficiently below the current sharing temperature during the tokamak pulsed operation, in order to preserve their SC properties. For that purpose, a He refrigerator is used. During the cooldown, it provides the boundary conditions (He temperature THe...
On the purpose to upgrade the code package of SUPERMAGNET-based hydraulic model, coupled 1-d flows at the multifunction branch is carefully explored not only in the context of hyperbolic PDEs, but also about the numerical stability in coupled solver models of co-simulation method. Comparing with the conventional method in other competitive tools like the ThermoPower package with Openmodelica,...
The China Fusion Engineering Test Reactor (CFETR) is the next device in the roadmap for the realization of fusion energy in China, aiming at bridging the gap between the fusion experimental reactor ITER and the demonstration reactor (DEMO).
CFETR will operate in two phases: steady state operation and self-sufficiency will be the two key issues for Phase I, with a fusion power of up to 200 MW,...
The optimal design of the next generation of accelerator magnets calls
for a high current density in the superconducting coil, which makes
the magnet protection a challenge. Quenches in the high-field magnets
for the High Luminosity LHC Upgrade typically develop within tens of
ms, and the reaction time needs to be comparable, requiring active
firing of heaters or other heat deposition...
