Searching for CesrTA guide field nonlinearities in beam position spectra

This project consisted of looking for nonlinearities using the beam position spectra for the Cornell Storage Ring. With the intent of finding new ways of locating non-linear errors in the magnet set-up. The main part of this project consisted of examining several different non-linear effects to ensure that they produced the expected results. These effects contribute to two different methods for discovering non-linearities. These effects were tested using both simulations and data from the Cornell Storage Ring. It has been shown that these effects are large enough that they can be seen clearly above the noise level in data from the Storage Ring. These effects can be tested using different lattice arrangements, in order to discover how the lattice arrangement effects these non-linear effects. This in turn can lead to a method for discovering and correcting non-linear errors.
