CFETR，“中国聚变工程试验堆”，是一个新的托卡马克装置。它的磁体系统包括环向场（TF）、中心螺线管（CS）和极向场线圈。本研究的主要目标是建立一个聚变功率为50-200 MW、包层自给的聚变工程托卡马克堆。CS和TF的最大磁场将达到15 T左右，这远远高于其他反应堆。新材料可用于开发下一代聚变反应堆的磁体技术。Bi_2Sr_2CaCu_2Ox被认为是一种很有潜力的超导磁体材料。ASIPP正在进行一项研发活动，以验证基于Bi 2212导线的电缆导管导体的可行性。设计并制作了一根42芯的亚尺寸导线。本文详细介绍了Bi-2212导体样品的制造过程和首次试验结果，包括导线规格、布线和压实工艺、导体热处理以及交流损耗和临界电流的试验结果。
The CFETR, “China Fusion Engineering Test Reactor,” is a new tokamak device. Its magnet system includes the toroidal field (TF), central solenoid (CS), and poloidal field coils. The main goal of this study is to build a fusion engineering tokamak reactor with fusion power of 50–200 MW and self-sufficiency by blanket. The maximum field of CS and TF will get around 15 T, which is much higher than that of other reactors. New materials could be used to develop the magnet technology for the next generation of fusion reactors. Bi2Sr2CaCu2Ox is considered as a potential material for the superconducting magnets. An R&D activity is running at ASIPP for the feasibility demonstration of cable-in-conduit conductor based on the Bi2212 wire. One subsize conductor cabled with 42 wires was designed and manufactured. In this paper, the manufacturing procedures and first test results of Bi-2212 conductor samples are described in details, including wire specifications, cabling and compaction process, conductor heat treatment, as well as test results on ac loss and critical current.
