A toast to Mister Superconductor

8 Dec 2008 - Sabina Griffith
Not part of the Procurement Arrangement, but excellent results are always worth a toast: the ITER Magnet Division and colleagues raise their glasses to Alexander Shikov, Vice-Director of the Bochwar Institute in Moscow.

Last week, the heads of the ITER Magnets Division, Neil Mitchell and Arnaud Devred, together with Deputy Director-General Gary Johnson, colleagues-that-have-turned-friends from other departments, and the European Domestic Agency took the chance to raise their champagne glasses to Alexander Shikov, Vice-Director of the Bochwar Institute in Moscow and the mastermind behind the outstanding efforts invested by Russia in the development of the ITER superconductors.

The Bochwar Institute is building on more than 40 years of experience on manufacturing superconductors made of niobium-titanium and niobium-tin. The first-in-the-world superconductiing magnet systems of the T-7 and T-15 tokamaks were fabricated out of these developed superconducting strands.

The production of the conductors for ITER's magnets is the biggest-ever procurement for the Bochwar Institute—some 120 tonnes of niobium-titanium (NbTi) for the poloidal field conductors and 100 tonnes of niobium-tin (Nb3Sn) for the toroidal field conductors to be produced at the Chepetsky Mechanical Plant. This totals to about one-fifth of the total amount needed for the construction of the ITER magnet system.

The latest testing of NbTi and Nb3Sn conductors have confirmed their highest quality and the soundness of the ITER toroidal and poloidal field conductor designs.
