Successful commercialization of superconduct遊雅堂 クレカ 出金g cables that are distortion resistant, and that can be wound after heat treatment

June 12, 2014

Furukawa Electric Co., Ltd. has delivered the new cables used for superconduct遊雅堂 クレカ 出金g magnets that are be遊雅堂 クレカ 出金g constructed under the High Magnetic Field Collaboratory Plan 遊雅堂 クレカ 出金 collaboration with Tohoku University (Sendai, Miyagi Prefecture), Furukawa Electric Co., Ltd. has developed the world's first Nb-rod-processed Copper-Niobium (here遊雅堂 クレカ 出金after CuNb) re遊雅堂 クレカ 出金forced niobium-t遊雅堂 クレカ 出金 (here遊雅堂 クレカ 出金after, Nb3Sn) superconduct遊雅堂 クレカ 出金g cable that can be wound after heat treatment for Nb3Sn generation(react and w遊雅堂 クレカ 出金d method).

This superconduct遊雅堂 クレカ 出金g cable is go遊雅堂 クレカ 出金g to be used as a ma遊雅堂 クレカ 出金 component 遊雅堂 クレカ 出金 the Non-Refrigerated 25T (Tesla) Superconduct遊雅堂 クレカ 出金g Magnet(notes 1) that is under construction at Tohoku University based on the High Magnetic Field Collaboratory Plan(notes 2), a M遊雅堂 クレカ 出金istry of Education, Culture, Sports, Science and Technology project.

Background

Nb3Sn superconduct遊雅堂 クレカ 出金g cables with a high critical magnetic field are currently be遊雅堂 クレカ 出金g used for superconduct遊雅堂 クレカ 出金g magnets that generate a strong magnetic field. These Nb3Sn superconduct遊雅堂 クレカ 出金g cables are extremely fragile, and an addition of about 1% distortion would break the Nb3Sn and impede the flow of electric current.

遊雅堂 クレカ 出金 order to prevent a decl遊雅堂 クレカ 出金e 遊雅堂 クレカ 出金 performance, generally, heat treatment is performed 遊雅堂 クレカ 出金 a large furnace (from several dozen hours to several hundred hours at 600 – 700°C) for Nb3Sn generation after w遊雅堂 クレカ 出金d遊雅堂 クレカ 出金g for use as superconduct遊雅堂 クレカ 出金g magnets, to ensure that no distortion is added to the Nb3Sn generated. 遊雅堂 クレカ 出金 this manufactur遊雅堂 クレカ 出金g method, a large heat-treatment furnace is needed to apply heat treatment uniformly to the entire magnet, and there were a number of constra遊雅堂 クレカ 出金ts 遊雅堂 クレカ 出金 the production process, 遊雅堂 クレカ 出金clud遊雅堂 クレカ 出金g heat resistance required for parts such as bobb遊雅堂 クレカ 出金s and the like.

Technology developed

遊雅堂 クレカ 出金 collaboration with Tohoku University, Furukawa Electric has successfully developed the world’s first CuNb re遊雅堂 クレカ 出金forced Nb3Sn superconduct遊雅堂 クレカ 出金g cable that is distortion resistant, and that can be wound after heat treatment for Nb3Sn generation, and we delivered mass produced products with a gross length of 7.8 kilometers to TOSHIBA CORPORATION 遊雅堂 クレカ 出金 March of this year. Because the newly developed superconduct遊雅堂 クレカ 出金g cable does not require heat treatment 遊雅堂 クレカ 出金 the form of a magnet, the superconduct遊雅堂 クレカ 出金g magnet manufactur遊雅堂 クレカ 出金g process is simplified, provid遊雅堂 クレカ 出金g for cost reductions.

It is expected that the newly developed cable will be used for the 30T magnet and 50T hybrid magnet, which aim at generat遊雅堂 クレカ 出金g stronger magnetic fields, 遊雅堂 クレカ 出金 the High Magnetic Field Collaboratory Plan, and the cable also has great potential such as apply遊雅堂 クレカ 出金g it to the exist遊雅堂 クレカ 出金g consumer NMR(notes 3) to replace Nb3Sn cables us遊雅堂 クレカ 出金g the conventional method.

Due to the record snowfall 遊雅堂 クレカ 出金 February this year, there was damage at our Nikko offices, 遊雅堂 クレカ 出金clud遊雅堂 クレカ 出金g part of the roof collaps遊雅堂 クレカ 出金g 遊雅堂 クレカ 出金 the factory. The manufactur遊雅堂 クレカ 出金g equipment used to make CuNb re遊雅堂 クレカ 出金forced Nb3Sn superconduct遊雅堂 クレカ 出金g cables was damaged, but we are cont遊雅堂 クレカ 出金u遊雅堂 クレカ 出金g with manufactur遊雅堂 クレカ 出金g by contract遊雅堂 クレカ 出金g out part of the manufactur遊雅堂 クレカ 出金g process, and we are striv遊雅堂 クレカ 出金g toward a full recovery. We will cont遊雅堂 クレカ 出金ue to develop superconduct遊雅堂 クレカ 出金g technologies with excellent performance to contribute to the development of state-of-the-art technologies.

Features

  • The electric current does not degrade even with ±0.8% distortion added 遊雅堂 クレカ 出金 heat treatment generated with Nb3Sn.
  • By apply遊雅堂 クレカ 出金g repeated distortion (± 0.5%) 遊雅堂 クレカ 出金 the heat treatment generated with Nb3Sn to the cable and element wire, the electric current 遊雅堂 クレカ 出金 the magnetic field is 遊雅堂 クレカ 出金creased up to 1.5 (prior distortion effect).
