ABSTRACT:
The quality of superconducting cavity resonators depends to a very great extent on the surface quality of the cavities. The invention relates to a process for the manufacture of superconducting cavity resonators with improved surface quality, whereby even complex shaped cavity resonators can be made with cavities coated with NbN.
