Proton synchrotron RF cavity mode damper tests

Abstract

A versat,ile, broad frequency range, rf cavity mode damper has been described in a previous paper.' A mode damper of this type has now been designed, constructed, installed, and tested on an existing 50 MHz synchrotron cavity. Measurements on the combined system have been completed, affording a comparison of analytical predictions with actual performance. The results of the measurements confirm the predict,ed efficacy of the mode damper up to 1000 MHz.
