Abstract : Efforts were continued on the establishment of a PEM for the BL-221 70Gc magnetron. Storage test data on previously manufactured tubes with Bomac facility hot hobbed and machined anodes was compiled. Electrolytic polishing and vacuum firing appears to provide adequate cleanliness of the anode to insure good tube performance. Additional work done with smaller anode boreout diameter did not result in producing the desired effect in the peak anode voltage. New anode cathode design changes worked out, appeared adequate in resolving the peak anode voltage problem. Revisions in test specifications were made and put into effect. New tubes were built with modified anode-cathode dimensions resulting in an adequate solution of the peak anode voltage problem. (Author)
