required 3.45 T bending field for 100 GeV/amu ions

superconductor used is the same as that used for
the outer coil of the Superconducting Super
Collider (SSC) magnet. Figure 5 shows a cross sec-

Although there are less dipoles than there
are quadrupole and corrector magnets, the arc
dipoles nevertheless remain the dominant cost item
in the machine. For this reason, the R&D effort
has focussed on this device. Various models have
been built, including four in industry,
culminating in a half-length model with prototype
cross section that was built and tested in the past
