The contribution is aimed at discussing the solidification mechanisms of metal parts produced by Additive Manufacturing (AM), especially focussing on Laser Powder Bed Fusion technology (L-PBF). The typical microstructure, surface features and possible defects are analysed to highlight expected differences with respect to part produced by traditional routes.
Our research focuses on exploitation the potential of AM for S- and C-band RF cavities made from pure copper.Prototypes of a 5-cell S-band drift tube resonator and side-coupled cavity cells, commonly used in linac systems for medical and industrial applications, have been successfully additively manufactured. Evaluation of these prototypes reveals that AM cavities perform comparably to...
Experience on AM produced accelerator components have been made since quite a few years and the community can now build on the numerous insights and results from these projects. This contribution will draw conclusions with respect to H-mode drift tube structures and make some suggestions for possible next steps. Some related beam dynamics studies will check which drift tube arrays are...
