Abstract
A tuning mechanism for a superconducting radio frequency particle accelerator cavity, wherein the cavity comprises a number of axially aligned cells held by a frame, with at least one active cell that is axially stretchable to tune the resonant frequency of the cavity. The tuning mechanism comprises a lever arm having a center of rotation, one or more mechanical members coupling the lever arm to an active cell, and a motor adapted to move the lever arm, to thereby move the active cell through the mechanical members.
