Radiation Damage Limitations for the Fermilab Energy Doubler/Saver

One important factor determining the lifetime of particle accelerators using superconducting magnets is the accumulated radiation damage of the magnet components. Using existing damage studies and a measured correlation between the radiation levels with the beam-off and the beam-on, a reasonable assessment of magnet lifetimes can be made. On the basis of this assessment it is expected that damage to the magnet conductor will not limit the magnet performance. The proper choice of polymeric materials used in the magnet is necessary to avoid frequent refurbishing of the magnets.
