The state-of-the-art magnetron engineering is lacking reliable methods capable of forecasting cathode's service life and its operational capacity in a low-temperature environment, thus the consistency of these parameters with the specification requirements can be assessed only by means of field tests of an inspection bath. No concurrent views can be traced either in the related research reports as for how to estimate the emissive ability of cathode material for crossed-field devices. It seriously complicates the sound and well-grounded choice of cathode's parameters for every individual device. Several lots of Pd−Ba material, which is used in the cathode being manufactured for commercial magnetrons, have been inspected. The transient condition of turning the autoemission into the explosive emission has been checked by estimating magnetron's operation capacity under a pulse ratio significantly exceeding the specification requirements. The results obtained in course of the research enabled us to make a conclusion about a correlation between magnetron's service life and its operation capacity under low temperatures. The proposed assessment criterion is the peak performance value and the experimentally established value of the pulse ratio, corresponding to the onset time to reach the full operative mode at the first launch of the magnetron under regular environmental conditions. The developed method provides a 100 % forecasting as for specification requirements consistency in terms of durability. This method is identical to the frost resistance test, though under normal environmental conditions.
