Abstract:

The technique for tuning hybrid permanent magnet quadrupoles which is employed for the Recycler Ring Quads\cite{MT15:rrq} employs harmonic measurements of the strength and low order harmonic components. The matrix for tuning was determined empirically. Finding the correct signs is a simple analytic exercise which we will perform as a check on the harmonic measurement results.
