Description
Compared with subtractive manufacturing methods such as CNC machining, additive manufacturing (AM) enables the fabrication of highly complex monolithic geometries. As a result, AM can improve functionality and reduce manufacturing costs. For linear accelerator (linac) components, this potential has been demonstrated in a growing number of studies and prototype developments. At the same time, recent advances in AM, particularly in metal powder-based processes, have significantly reduced earlier limitations related to linac-specific requirements such as vacuum outgassing and RF electrical conductivity. AM has therefore become a promising approach for the fabrication of linac components. It enables designs that are difficult or impossible to produce by conventional methods, including highly complex cooling structures and multimaterial components. Despite these advantages, conventional fabrication methods are still often preferred. This short review summarizes recent progress in the additive manufacturing of linac components. It discusses several successfully manufactured prototypes and shows which linac-specific requirements can already be fulfilled by AM today.
