Tuning of radio frequency (RF) accelerator cavities in electron storage rings is needed to maintain accelerating gap voltage under varying beam loading conditions. A new type of ferrite tuner based on stripline configuration has been tested at the National Synchrotron Light Source (NSLS). The tuner is basically a short-circuited ferrite-loaded transmission line which is inductively coupled to the RF cavity to be tuned. The use of substituted yttrium iron garnet (YIG) allows for custom tailoring the saturation magnetization to the specific application and thus minimizing the bias field requirement. The design goal for the tuner was to achieve a tuning range of 50 KHz. The authors were able to demonstrate linear tunability of 78 KHz, exceeding the goals set for the tuner. Results of testing the YIG tuner are presented.
