Abstract: An indirectly heated button cathode for use in the ion source of an ion implanter has a button member formed of a slug piece mounted in a collar piece. The slug piece is thermally insulated from the collar piece to enable it to operate at a higher temperature so that electron emission is enhanced and concentrated over the surface of the slug piece. The slug piece and collar piece can be both of tungsten. Instead the slug piece may be of tantalum to provide a lower thermionic work function. The resultant concentrated plasma in the ion source is effective to enhance the production of higher charge state ions, particularly Pnullnullnull for subsequent acceleration for high energy implantation.

Abstract: A cathode for an electron tube provided with a base containing at least one kind of reducing agent, a metal layer whose main component is tungsten formed on the base, and an electron emission material layer whose main component is an alkaline-earth metal oxide including barium formed thereon, deformation of the base in operation is controlled by composing the metal layer with a porous metal layer and limiting the thickness and the porosity of the metal layer. As a result, it is possible to achieve a cathode for an electron tube applicable to a cathode-ray tube for a display in which the cutoff voltage is liable to change.

Abstract: An electron gun cathode structure includes a support member made of an insulating material, a first grid fixed to the support member, and a cathode disposed on the side of the support member opposite to the first grid. A thermal expansion .DELTA.L.sub.s /L.sub.s of the insulating material constituting the support member due to heat from the cathode is larger than a thermal expansion .DELTA.L.sub.G /L.sub.G of a material constituting the first grid due to heat from the cathode. A manufacturing method of an electron gun cathode structure includes preparing a member including a first face and a second face having a step therebetween, a height of the step being equal to a predetermined distance d.sub.12, placing a first grid on the first face, placing a spacer on the second face, placing an insulating support member on the first grid and the spacer, and grinding a top surface of the spacer opposite to its surface that is fixed to the support member so that an actual distance d.sub.12 becomes a desired value. Further, a distance d between the top surface of the spacer and a cathode is measured with a non-contact type distance measuring instrument, and a position of the cathode with respect to the first grid is so set that a difference d-d.sub.12 becomes a desired value.
