Abstract
The invention relates to linear beam amplification devices having an electron emitting cathode and an RF modulated grid closely spaced therefrom, and more particularly, to a novel support structure for the grid that accommodates thermal expansion while maintaining an optimum grid-to-cathode spacing.
Claims20
A linear beam device having an axially centered cathode and an anode spaced therefrom, said anode and cathode being operable to form and accelerate an electron beam, said linear beam device comprising:
- an axially centered grid positioned between said cathode and said anode, 5 said grid being operable to accept a high frequency control signal to density modulate said electron beam;
- a grid support in contact with said cathode;
- and
- means for holding together said grid support and said grid.
1 more element
A linear beam device having a cathode and anode, comprising:
- a grid positioned at a predetermined distance from said cathode and being between said cathode and said anode, said grid being operable to accept a high frequency control signal to density modulate a beam;
- a grid support supporting said grid and being operable to maintain said predetermined distance between said cathode and said grid throughout the operating temperature range of said linear beam device.
