4 frames out of 13

7 Nov 2022
Judging by the first elements of its steel structure, the Neutral Beam High Voltage Building, located adjacent to the Tokamak Complex, will be a spectacular addition to the ITER platform.

In a little more than one week, 4 out of the required 13 steel frames (15 to 25 metres tall) for the Neutral Beam High Voltage Building have been bolted to the concrete slab. Running alongside the Tokamak Complex, the building will extend 84 metres in length and 28 metres in width.
Neutral beams are fluxes of high-energy particles that have two functions in ITER: one is to deliver heating power to the plasma and the other is to probe it for diagnostic purposes.

Whether for heating or for diagnostic measurement, the massive neutral bean injectors require specific power supply systems.

The Neutral Beam High Voltage Building (B37) will comprise three halls; the smallest, whose steel structure is being erected, will host the power supply systems for the diagnostic neutral beam, while the two largest will each be home to the massive high-voltage decks, their giant bushings, and the transmission lines that will deliver 1 MV of ultra-high voltage to the heating neutral beam injectors.

In a little more than one week, four out of the required 13 steel frames (15 to 25 metres tall) have been bolted to the concrete slab. Running alongside the Tokamak Complex, the building will extend 84 metres in length and 28 metres in width.

Once clad in ITER's signature mirror-like stainless steel and dark grey-lacquered metal, B37 will look like any large building on the platform. The equipment and systems it will accommodate have no equivalent in the world.
