US Patent:

48734683, Oct 10, 1989

Filed:

May 16, 1988

Appl. No.:

7/194638

Inventors:

George V. Miram - Atherton CA
Michael C. Green - Palo Alto CA
George K. Merdinian - Los Altos CA

Assignee:

Varian Associates, Inc. - Palo Alto CA

International Classification:

H01J 3304
H01J 2958
H01J 1904

US Classification:

313411

Abstract:

A gun for generating a multiple sheet beams 50 of electrons has a flat surfaced cathode 10 with parallel protruding ridges 12 of non-emitting material forming parallel focus electrodes for the sheet beamlets. A control grid of parallel bars 14 is aligned with the ridges 12 to reduce grid interruption. The beamlets may be focussed between support bars 54 of a foil anode 52 for passing the beam into a high-pressure volume such as a gas laser 48. The ridges are formed by inserting non-emissive bent sheets into grooves 58 in the cathode, which are dovetailed to hold them.
