The high-current-carrying rectangle shape low-temperature superconducting magnet, as part of project from CASIC, which was developed by a team from ASIPP, passed examination of experts on an online project review meeting on May. 17.
With 1278mm long and 598mm wide, this compactness structure has 2738 amperes-turns. Wound by NbTi/Cu superconducting wire, the maximum operating current density can reach 176A/mm2@4.6K and 5.96T that is at the leading level of the same type.
After 15 rounds of “training” testing, the magnet can operation steady under 330A@4.6K, 5.96T.
Prof. ZHENG Jinxing, who are on behalf of the R & D team, made a report on electromagnetic & structure design and analysis, manufacturing process and cryogenic electrical test results.
Experts agreed that the team has completed the electromagnetic and structural scheme design. Aside from that, they innovated the vacuum pressure impregnation (VPI) primary molding process to complete the magnet insulation curing.
