FPS-85 TUBE IMPROVEMENT PROGRAM 4CPX250K.

Abstract : The objective of the program was to investigate the areas where possible improvements could be made in order to provide tubes that would operate in the FPS-85 for a minimum of 4000 hours with a maximum of ten (10) arcs and a power output decrease not to exceed 3db. Also stressed in this program was the improvement of the mechanical strength of the cathode leader assembly to reduce the possibility of tube breakage due to rough handling or misalignment of tube sockets.
