Abstract:
There is an accuracy limit of LLRF control over cavity rf phase and amplitude. This limited accuracy of control gives rise to beam energy and phase jitter, emittance growth, and beam loss. In the case of the SNS linac, there are a few limiting factors such as minimizing injection foil miss, acceptable ring injection painting, and beam loss in the linac which are related with the LLRF control errors. We studied the impact of /spl plusmn/1/spl deg/ / /spl plusmn/1% and /spl plusmn/0.5/spl deg/ / /spl plusmn/0.5% rf phase and amplitude uncertainties to the linac using the Ltrace and Parmila codes.
