摘要： A device for use in a linear accelerator operable to accelerate charged particles along a beam axis is disclosed. The device includes a plurality of monolithic members connected to form a series of accelerating cavities aligned along the beam axis and coupling cavities. Each of the coupling cavities intersects with adjacent accelerating cavities at first and second coupling apertures. The first and second coupling apertures have different sizes.

摘要： A standing wave linear accelerator with a prebunching section and an accelerating section that are formed into a unitary accelerating structure is described. The prebunching section is configured to group charged particles into bunches by velocity modulation of the charged particle beam. The accelerating section has a plurality of inter-coupled resonant cavities, including an input cavity that is coupled to the prebunching section and an output cavity.

摘要： In a clinical linear accelerator system for delivering charged particles for medical applications, a series of monolithic cavity-defining members is connected to form a succession of accelerating cavities, with temperature regulation being achieved by aligning internal cooling passageways through the series of monolithic members. As a result, a continuous coolant flow path is formed through the monolithic members. At each member-to-member interface, there is a leakage-release path for non-intrusively conducting any leakage that occurs at the interface. In the preferred embodiment, there is a braze connection that separates the leakage-release path at an interface from the coolant flow path at that interface. The braze connection provides a seal that further safeguards against coolant entering an area in which performance of the system is affected.
