Performance of Superconductive Cavities made by AM technology by Nb or Cu with Nb thin spattered film on the internal surface


The aim of the deliverable D10.4 was to assess the manufacturability of seamless SRF cavities mad of copper or/and niobium by Additive Manufacturing technology. In particular, the employed technique is Laser Powder Bed Fusion (LPBF).

The effectiveness of the process was successfully demonstrated both for copper and niobium. After intense studies for the evaluation of process parameters, the SRF cavities were produced. Surface treatments were performed in order to reduce the surface roughness of the AMed parts to achieve the surface roughness target value of 1 µm.
