  This paper describes a new design of superconducting dipole magnet prototype
by the use of tilted solenoids. The magnet prototype, which consists of four
layers of superimposed tilted solenoids with operating current of 3708 A, will
produce a 2.5 T magnetic field in an aperture of 50 mm diameter. The detailed
magnetic field design by using two kinds of software is presented. And their
results show a good agree in the magnetic fields. So far we have accomplished
the prototype construction and expect a cryogenic test. The process of the
magnet fabrication is also reported in detail.
