Magnetic Shield Cold
Magnetic Shield Warm • Will be fixed on the vacuum vessel • Not easy to have space for overlaps in joints (top plate, lateral windows) Not sure we have space for that
Magnetic Shield Warm • Geometry • 3 D • 2 mm thickness • 2 x 1 x 1 m • Material • Mu-metal • Gaps between top plate and other plates • Excitation: 60 µT

Support System • Thermal design still to be finalized. Trade-off between symmetrical contraction (blades vs FPC) and thermal loads • Need to advance on supporting jacks (calculate modes of vacuum vessel + tanks)
