Low-loss 9-cell 1.3GHz cavities have been developed at KEK aiming at a high-gradient operation for the International Linear Collider. One of the most important issues to realize such a high gradient in a pulsed operation of super-conducting cavities is how to compensate the Lorentz detuning. The Lorentz detuning of the cavity amounts to 3kHz at our goal of 45MV/m acceleration field. None of the tuners to date have achieved this range. A coaxial ball-screw tuner was designed and proved to reach… CONTINUE READING
