Data are presented to establish the operating characteristics of the proposed ISABELLE ring magnets. The harmonic content of both the straight section and ends of the magnets was measured as a function of magnetic field with the correction coils energized or disconnected. The magnets are single layer cos N/sub theta/ turns distribution superconducting saddle coils with ''cold'' iron shields. The data presented also include quench performance of magnets vs the critical current performance of the wire strands; the rate effect on the harmonic content of the field; the magnetization loss of the magnets; magnetic length; magnetic field vs current/turn; and magnetic field external to the iron shield. The maximum performances of the dipoles and quadrupoles are 4.9 T and 4.6 T (bore field 2-D) with a design requirement of 3.93 T and 3.28 T respectively. Magnets of both types have exceeded the design field on the first quench. The field characteristics are well within the present design requirements for ISABELLE.
