MONOLITHIC STRUCTURE WITH INTERNAL COOLING FOR MEDICAL LINAC

摘要

In a clinical linear accelerator system for delivering chargedparticles for medical applications, a series of monolithic cavity-definingmembers is connected to form a succession of accelerating cavities, withtemperature regulation being achieved by aligning internal coolingpassageways through the series of monolithic members. As a result, acontinuous coolant flow path is formed through the monolithic members. Ateach member-to-member interface, there is a leakage-release path for non-intrusivelyconducting any leakage that occurs at the interface. In thepreferred embodiment, there is a braze connection that separates theleakage-release path at an interface from the coolant flow path at thatinterface. The braze connection provides a seal that further safeguardsagainst coolant entering an area in which performance of the system isaffected.
