ITER Magnet Feeder: Design, Manufacturing and Integration

Abstract

The International Thermonuclear Experimental Reactor (ITER) feeder procurement is now well underway. The feeder design has been improved by the feeder teams at the ITER Organization (IO) and the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) in the last 2 years along with analyses and qualification activities. The feeder design is being progressively finalized. In addition, the preparation of qualification and manufacturing are well scheduled at ASIPP. This paper mainly presents the design, the overview of manufacturing and the status of integration on the ITER magnet feeders.

The design of YBCO binary current leads and its electromagnetic-thermal coupling analysis based on PEEC and finite volume method

“…HTS binary current leads were first proposed by Mumford in 1989 [3]. In the past few years, HTS binary current leads have been widely applied, not only in large-scale systems, such as particle accelerators [4][5][6][7] and fusion devices [8][9][10][11][12][13], but also for smaller isolated magnets, such as superconducting magnetic resonance imaging (MRI) magnets [14,15], high-field magnet system [16][17][18][19][20][21] and other special test facilities [22][23][24][25][26][27][28][29][30]. The typical structure of binary current leads comprises two parts: a hightemperature portion made by a normal conductor and a lowtemperature portion made by an HTS and a normal metal shunt.…”
