The paper presents mainly the design of a Superconducting Dipole With Cold Iron, the parameters selected for the iron shield, the effect of iron shield on field in bore and the results of experiment. The dipole is made of NbTi brald of 29 strands. Each strand has a diameter of 0.3 mm and the smallest ratio of copper to superconductor (1:1). The conductor is wrapped by mylar tape as insulation. The cross section of the conductor is 0.8 × 5.9 mm2. This dipole has 10 cm inner diameter, 15.2 cm outer diameter and 46 cm outer diameter of cold iron. It is excited both by direct current and by pulse current. Very little training is observed at full field. After four times of quench, the field normally reached 4.6T at 1190A. The magnet current was about 89% of short sample. The field of dipole with cold iron shield increases in bore by 30% over the field of dipole without iron shield.
