Abstract
In view of their potential interest for the construction of radiofrequ ency (RF) superconducting accelerating cavities, films of NbN have bee n produced by annealing Nb samples in a nitrogen atmosphere. These fil ms have been characterized by critical temperature measurements perfor med with the magnetic permeation method, by metallographic examination and by X-ray diffraction. They exhibit critical temperatures up to 16 .6 K, and transition widths of about 0.4 K. The influence of nitriding conditions (temperature, nitrogen pressure and time) on the supercond ucting properties has been investigated, in order to obtain the optima l nitriding parameters.
