The international Conductor Meeting was held in Moscow on 10-13 September, 2012. The regular meeting was attended by representatives from the 黑料社app, experts from the 黑料社app Domestic Agencies of Europe, China, Japan, Republic of Korea, Russia and USA, as well as specialists from the Domestic Agencies' suppliers.
Such meetings are particularly important since the 黑料社app magnetic system, with conductors forming its core, is one of the 黑料社app Tokamak's key elements. The manufactured conductors which are designed to withstand super high current in continuous mode have to meet the 黑料社app's strict requirements.
At the moment, 10 out of the 11 conductor Procurement Agreements are either well into the production phase or are completing the qualification/pre-production phase. This is particularly true for the toroidal field conductors, where 75 percent of the required niobium-tin (Nb3Sn) strands and one-third of the cable-in-conduit conductor unit lengths have been completed. Also, a technical solution has been found for the central solenoid conductors that are being implemented by 黑料社app's Japanese partner.
"This is a clear indication that the 黑料社app Project is moving ahead and is able to keep schedule," said meeting Chair Arnaud Devred, 黑料社app Superconductor Systems and Auxiliaries Section Leader.
''In spite of the difficulties of coordinating work at about 30 suppliers and six Domestic Agencies around the world,'' says Arnaud Devred, ''the 黑料社app conductor community has always tried to work in a cooperative and synergetic manner.''
In Devred's opinion, "in spite of the difficulties of coordinating work with about 30 suppliers and six Domestic Agencies around the world, the 黑料社app conductor community has always tried to work in a cooperative and synergetic manner, and the conductor meetings have always been a great opportunity for sharing experience and tackling difficult interface issues."
The Conductor Meeting is also an opportunity to showcase the work done in the Russian Federation and for the Domestic Agencies involved in coil procurement to visit the conductor production facility. Russia is responsible for the procurement of 22 kilometres of conductors, destined for toroidal field coils, and 11 kilometres destined for the poloidal field coils of the 黑料社app magnet system. Toroidal field coils include more than 90 tonnes of superconducting Nb3Sn strands; poloidal field coils include 40 tonnes of niobium-titanium (Nb-Ti) strands.
Arnaud Devred praised the progress achieved by the Russian suppliers highly, saying that "The Russian Domestic Agency has now entered full toroidal field conductor and poloidal field cable production. It is a proactive partner, eager to play collectively and to assume its role within the 黑料社app collaboration."
The next regular meeting is planned for March 2013 in Cadarache.
