| Title | Microstructural and superconducting radiofrequency (SRF) properties of multilayer sequentially sputtered Nb3Sn films | ||||
| Abstract | Nb3Sn is considered as a potential candidate for superconducting radiofrequency cavities for particle acceleration due to its higher transition temperature of 18.3 K and higher superheating field of 400 mT. Nb3Sn films can be grown inside the surface of a Nb cavity by sequentially sputtering multiple layers of Nb and Sn thin films followed by annealing at 950 °C for 3 h. Here we report the microstructure analysis of Nb3Sn films grown on Nb substrates. The films crystal structure, surface morphology, and compositions were characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy respectively. The films had polycrystalline Nb3Sn structure with fine grain surface and an atomic Sn composition of ~23%. We also report the RF surface resistance of this film under different temperatures at 7.4 GHz to understand the feasibility of this method for the SRF application. The RF surface resistance of the films fabricated from magnetron sputtering were | ||||
