Abstract

AN ELECTRON GUN CATHODE COMPRISING A CATHODE MATERIAL (10) FOR EMITTING ELECTRON, A BASE (20) ON WHICH SAID CATHODE MATERIAL (10) IS DISPOSED, A HEATER (50) AND A CYLINDRICAL SLEEVE (30) ON WHICH SAID BASE (20) IS MOUNTED AND ENCLOSING THE HEATER (50), WHEREIN SAID SLEEVE (30) INCLUDES A BOTTOM (32) HAVING THROUGH-HOLES (32A) FOR THE PASSAGE TERMINALS (51) OF SAID HEATER (50), AND SAID HEATER (50) IS DISPOSED IN A CLOSED SPACE FORMED BY SAID SLEEVE (30) AND SAID BASE (20). A MANUFACTURING METHOD FOR THE ELECTRON GUN CATHODE IS ALSO DISCLOSED.THE CATHODE OF THIS INVENTION PROMOTE THE THERMAL EFFICIENCY AND INHIBITS THE HEAT LOSS BETWEEN THE BASE AND THE SLEEVE. (FIG. 2)
