Abstract

See full text

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.
