In accordance with the work program for the restoration of klystrons, a cycle of studies was carried out, which includes X-ray fluorescence analysis of the composition of the emitter layer and core of oxide cathodes with different degrees of operating time. Studies have been conducted to assess the possibility of using and predicting the resource, both restored and used cathodes. Studies were conducted to assess the possibility of using and predicting the resource, both restored and used cathodes. The analysis was performed using a Bruker S8 TIGER WDXRF spectrometer (X-ray tube power 4 kW, Rh-cathode, current up to 170 mA, voltage up to 60 kV), with Spectra Plus software package. Comparative analysis of the data obtained for emitters with different degrees of development can provide a fairly reliable estimate of the efficiency and resource of the cathodes.
