The design and construction of a superconducting solenoid generating a magnetic field of high homogeneity is discussed. The design is based on the Garrett mathematical description of a magnetic field produced from a set of axially symmetric coils. The experimental results for a 1.75-in. ID solenoid, operating at either 10 or 24 kilogauss and possessing end-correcting coils in an arrangement determined by theory, indicate a central field homogeneity of 1/105 over about 1 in. at 10 kilogauss and 0.75 in. at 24 kilogauss. At approximately 9.4 kilogauss it was possible to clearly resolve the three chemically shifted proton NMR peaks of ethyl alcohol. This result indicated a homogeneity of 1/106 over the sample at a single point in the accessible field volume.
