Claim Text:
1. A variable vacuum capacitor comprising: a vacuum enclosure, a first variable electrode assembly comprising one or more first static electrodes and one or more first mobile electrodes, a second variable electrode assembly comprising one or more second static electrodes and one or more second mobile electrodes, a first electrical connection terminal for providing an electrical connection to the one or more first static capacitor electrodes, a second electrical connection terminal for providing an electrical, connection to the one or more second static capacitor electrodes, displacement means for displacing the first and/or second mobile electrodes relative to the first and/or second static electrodes respectively, along an axis of the vacuum capacitor, wherein, in the variable vacuum capacitor, the first and second electrode assemblies are ganged along the axis such that the first mobile electrode assembly is offset along the axis by a gang offset distance from the second electrode assembly, and the variable vacuum capacitor comprises mobile electrode linkage means for providing a kinematic linkage between the one or more first mobile electrodes at a first position along the axis and the one or more second mobile electrodes at a second position along the axis, such that a first displacement along the axis of the one or more first mobile electrodes results in a second displacement along the axis of the one or more second mobile electrodes.
