Abstract:
The Recycler Ring utilizes a total of 344 combined function and 88 quadrupole magnets to provide optical focusing. Since these are all
permanent magnets, construction of a ring with the expected optical characteristics requires that the magnetic field gradient in these elements
be close to the design value. The purpose of this note is to quantify the impact on Recycler horizontal and vertical b-functions, tune, and
coupling of both systematic and random gradient errors in the combined function and quadrupole magnets. Both normal and skew gradients
are considered.
