  In order to achieve higher luminosities in Run II a separate antiproton
storage ring was built in the Main Injector tunnel. To reduce both construction
and operations costs permanent magnets were used. This paper discusses the
design criterion and specifications, including temperature dependence,
longitudinal uniformity, and adjusting of the higher harmonics of the magnets.
The design tolerances for a storage ring are more stringent than for a single
pass beam line. The difference between the measured and ideal central field for
each magnet was held to better than 0.1%. The temperature stability for all
magnets was set to better than 0.01% per degree Celsius. Higher order harmonics
relative to the central field were set to less than 0.01%. This was done for
all 484 permanent magnet that were built.
