FIELD: manufacture of all types of straight-channel cathodes: molten, boride lanthanum, and the like cathodes. SUBSTANCE: cathode is manufactured by cutting vertical slots in cathode material through cathode height and heater thickness, welding of set of heaters, trimming of entire cathode-heater unit, followed by its polishing and separation of cathodes. EFFECT: improved stiffness and compensation of thermal expansion. 3 dwg
