We present succesful beam tests of an additively manufactured IH-Type linac structure with a 1.4 MeV beam from an Van de Graaff accelerator.
This work presents the development of additive manufacturing (AM) technology for the design and production of compact Radio Frequency Quadrupole (RFQ). Using PBF-LB/M with Cu-ETP material, the study focuses on advanced supportless design, cost-efficient manufacturing, and improved cooling performance. The research also covers AM post-processing, metrology, and validation for next-generation...
Additive manufacturing (AM) has proven to be a powerful technique for rapid prototyping and the fabrication of complex geometries. For use in a 433 MHz IH-DTL cavity, a CF40 coupler was developed and manufactured from high-purity copper using a 3D printing process. It incorporates a water-cooling concept that would be impossible to implement using conventional manufacturing methods. The...
Copper is known for its excellent thermal and electrical conductivity. The addition of alloying elements through the use of precipitation hardening significantly increases the strength of copper, with the challenge being to establish a balanced relationship between conductivity, strength, and ductility. At the Fraunhofer IWS, a green laser is primarily employed for selective laser melting to...
Plasma Electrolytic Polishing (PEP) is gaining increasing attention as a highly efficient surface treatment method, offering significant advantages over traditional polishing techniques. In several industrial sectors, PEP has already been fully integrated into commercial solutions; in others, it is still emerging as a promising alternative.
At INFN-LNL, PEP has been under continuous...
Additive manufacturing (AM) has become a powerful tool for rapid prototyping and manufacturing of complex geometries. A 433 MHz IH-DTL cavity has been constructed to act as a proof of concept for direct additive manufacturing of linear accelerator components. The original design of the cooling for the drift tube showed insufficient heat dissipation, leading to potential thermal deformation...
H-type structures are a dedicated candidate for cw operation because they can be cooled very efficiently. With the aid of additive manufacturing, in particular complicated and complex water-cooling channels inside stems and drive tubes can be realized. In a relatively small cw operated H-type buncher cavity with only a length of 540 mm and a diameter of 614 mm, rf power levels up to 24 kW were...
