The nitrogen doping (N-doping) treatment for niobium superconducting radio-frequency (SRF) cavities is one of the key enabling technologies that support development more efficient future large accelerators. However, N-doping results have diverged due to a complex chemical profile under nitrogen-doped surface. Particularly, industrial-scale production conditions, it difficult understand underlying mechanism thus hindering performance improvement. Herein, combination spatially resolved and...
