文摘A novel kind of SC（superconducting） solenoid coil is designed to satisfy the homogencity requirement of the magnetic field.In this paper,we first calculate the current density distribution of the solenoid coil section through the linear programming method.Then a traditional solenoid and a nonrectangular section solenoid are designed to produce a central field up to 7 T with a homogencity to the greatest extent.After comparision of the two solenoid coils designed in magnet field quality,fabrication cost and other aspects,the new design of the nonrectangular section of a solenoid coil can be realized through improving the techniques of framework fabrication and winding.Finally,the outlook and error analysis of this kind of SC magnet coil are also discussed briefly.
