[en] The R and D program of the superconducting model coil of HT-7U is in progress. A central solenoid model coil (CSMC) and a double-pancake toroidal field dummy coil (TFDC) have been designed and under fabrication in the Institute of Plasma Physics, the Chinese Academy of Sciences (ASIPP). CSMC has inner and outer diameters of 574 mm and 1140 mm respectively, height of about 485 mm and 216 turns in total. The peak field of it is 6.3 T with operating current of 18 kA. CSMC will be tested in ASIPP in the next year. TFDC is a 2/3 scale of toroidal field coil of HT-7U using a full size dummy conductor. A winding machine for cable-in-conduit conductor (CICC) coils has been constructed in ASIPP. (author)
