±¬×ߺÚÁÏ signs Procurement Arrangements with China and Europe
Last week, the ±¬×ߺÚÁÏ signed Procurement Arrangement number 6 and number 7. First, the ±¬×ߺÚÁÏ and the Chinese Domestic Agency signed a Procurement Arrangement for the unit length conductors for ±¬×ߺÚÁÏ's 18 superconducting toroidal field magnets. ±¬×ߺÚÁÏ Director-General Kaname Ikeda signed the document on behalf of the ±¬×ߺÚÁÏ; Cheng Jinpei, Standing Committee Member of National People's Congress, signed on behalf of the Chinese Domestic Agency.
The second Procurement Arrangement was signed between the ±¬×ߺÚÁÏ and the European Domestic Agency "Fusion for Energy" for the supply of ten toroidal field coils for the ±¬×ߺÚÁÏ magnet system. Outside of the vacuum vessel, the toroidal field coils are the biggest components of the ±¬×ߺÚÁÏ machine. Japan is going to build the other nine coils to complete the system.
"The toroidal field coils are an integral part of the ±¬×ߺÚÁÏ machine," Neil Mitchell, Head of the ±¬×ߺÚÁÏ Magnets Division, explains. "They weigh about 350 tons and have to come with an accuracy of 3 to 5 mm."
