The vacuum vessel is made of non-magnetic steel (304 LN) with a thickness of 10 mm. | The vacuum vessel is made of non-magnetic steel (304 LN) with a thickness of 10 mm. | ||
The octants with flanges have been manufactured separately and were assembled in-situ by welding. This assembly was done directly around the central conductor CC/HX, already placed in position. The CC/HX coil is outside of the vacuum vessel thanks to a helical groove built into the vessel. | The octants with flanges have been manufactured separately and were assembled in-situ by welding.
