The magnet in the beam line injection from a Separate Sector Cyclotron (SSC) to Cooling Storage Ring (CSR) was selected as CSR magnet fabrication's R&D. A method to obtain good field homogeneity was attempted in a C type dipole prototype. This method is not enlarged the dipole gap and need only two different very smaller power supply and easy operated and little cost. Because the C type dipole prototypes have a larger bending angle and smaller radius, it is very difficulty to stack and fabrication. The quadrupole prototype in the CSRm injection beam line is four fold assembly quadrupole. Its coils were made with a special vacuum epoxy impregnation technology, which is not necessary to use the complicated and expensive impregnating mold. Its maximum pole tip field was designed to reach near 10 000 Gs. All prototypes' fabrication and field measurement results will be present in detailed in this paper.
