Measurements on the coherent synchrotron radiation effects in SURF III beam

Abstract

In order to verify that the forming of consistent micro-bunches leads to bursts of coherent synchrotron radiation and to the self-cooling of the micro-bunches, three series of experiments have been performed on the SURF III ring. The experimental results are presented and discussed. They could explain the reasons for inducing coherent synchrotron oscillation with saw-tooth instabilities. A method to maintain the coherent synchrotron radiation and its cooling effect, while suppressing the instabilities, is submitted.
