Abstract
An electron tube comprises an evacuated envelope including an anode forming a section of the envelope and a plurality of alternatively-disposed metallic and insulating annular members. The anode includes an anode ring having a plurality of slots formed therein to provide stress reduction. The anode ring is attached to one of the metallic members thereby providing a low impedance electrical interconnection therebetween.
Claims7
In an electron tube comprising an evacuated envelope including an anode forming a section of said envelope, and a plurality of alternately-disposed annular metallic and insulating members, the improvement wherein said anode comprises
- an anode ring having stress reduction means formed therein, said anode ring being attached to one of said metallic members, thereby providing a low impedance electrical interconnection between said anode and said metallic member, said anode ring having a height, h, an inside radius, r, and a thickness, t, related by the formula h=0.5(rt).sup.1/2.
In a high power electron tube comprising an evacuated envelope including an anode forming a section of said envelope, an annular insulator, and an annular metallic member attached between said insulator and said anode, the improvement wherein said anode comprises
- an anode ring having a plurality of slots formed therein segmenting said ring into a plurality of flexible sections, each of said sections being attached to said metallic member, thereby providing a flexible, low impedance electrical interconnection between said anode and said metallic member.
