Abstract

A 352-MHz fast-ferrite tuner, manufactured by Advanced Ferrite Technology, was tested on a single-cell rf cavity at the Advanced Photon Source. Low-power rf testing was performed on the tuner-cavity combination to evaluate tuning range, bandwidth, stability, and compatibility with existing Advanced Photon Source low-level rf hardware. The test system comprises a single-cell copper rf cavity, a bipolar DC bias supply for the ferrite tuner, a water flow and temperature metering and interlock system, and a low-level rf cavity tuning loop consisting of an rf phase detector and a PID amplifier. Test data will be presented.
