Shuichi Noguchi, KEK6-th ILC School, November Frequency Tuner  RF Accelerating Cavities usually have Tuners.  They are used to tune the Cavity Resonance Frequency, in order to minimize the reflected RF power, usually.  Tuning Accuracy << Resonant Band Width  They must cover the Wide Range of the Fabrication / Pre-tuning Error.  Feed-back can be used in CW operation.

Shuichi Noguchi, KEK6-th ILC School, November The ILC Blade Tuner On the basis of the test results here presented the ILC Blade Tuner prototype is already close to fulfill all the XFEL and ILC specifications. The experience gained with the cold tests on the so called prototype has been used for the final revision of the Blade Tuner, currently under construction. The first 8 units for Fermilab have been produced and 2 more are under construction. Double Piezo
