Abstract
A thyratron includes a grid structure in which a grid element has a plurality of apertures therethrough, each of the apertures comprising two arcuate portions at different distances from the center of the grid which are connected by a radial portion. Thus a large grid area may be provided without detrimentally affecting voltage hold-off, jitter or mechanical soundness.
Claims9
A thyratron including a cathode, an anode, and a grid disposed between the cathode and the anode, said grid comprising a disk having an aperture therein and a center point;
- said aperture including:
- a first arcuate slot having as its center of curvature said center point of said disk, a second arcuate slot having as its center of curvature said center point of said disk, and a third slot disposed generally radially relative to said center point and connecting said first and second arcuate slots.
A thyratron including a cathode, an anode, and a grid disposed between the cathode and the anode, said grid comprising a body having a disk having a first aperture therein and a base portion arranged together with said disk;
- said first aperture having a first arcuate slot which is generally concentrically disposed about a first center point, a second arcuate slot which is generally concentrically disposed relative to the first center point, and a third slot disposed generally radially relative to the first center point and connecting said first and second arcuate slots;
- said base portion having a second aperture therein in communication with said first aperture, said second aperture having a first arcuate slot which is generally concentrically disposed about a second center point, a second arcuate slot which is generally concentrically disposed relative to the second center point, and a third slot disposed generally radially relative to the second center point and connecting said first and second arcuate slots;
- said first aperture and said second aperture being relatively disposed such that there is no direct line-of-sight between said anode and said cathode which passes through both said first and second apertures.
