Abstract
An RF cavity is provided with a plurality of tubes that are formed into a tubular cage in a predefined shape to define the RF cavity. A selected number of tubes and a selected tube diameter are provided to form a confinement cage for the RF fields within the RF cavity defined by the tubes. The multiple, small metal tubes are selectively bent to form different cavity shapes and sizes as needed to accelerate the particles and function as a confinement cage for the RF fields within the RF cavity defined by the tubes. The cost to fabricate RF cavities using the tubular cage design is significantly lower than the cost of producing a solid cavity using conventional fabrication technology.
