Grid for vacuum electron device and method for manufacture of same

A grid component for use in a vacuum electron device (VED) having an anode and an electron-emissive cathode, the grid component being mountable in an electron beam path between the anode and cathode and comprising:

• a dome bulging in a first direction and having a grid pattern formed thereon;
• an annular flange surrounding the dome;
• a skirt surrounding the annular flange and extending in a direction opposite the first direction, such that when the grid is mounted in the VED between the cathode and anode with the dome in confronting relationship to the cathode, the skirt extends from the flange towards the anode, the dome, the annular flange, and the skirt formed on a deposition surface that includes a skirt template;
• and
• one or more alignment orifices disposed in the annular flange.

A vacuum electron device (VED) comprising:

• an anode;
• an electron gun including a cathode configured to generate a beam of electrons that are directed towards the anode;
• a collector configured to receive electrons from the cathode;
• and
• a grid configured to modulate electrons from the beam of electrons, the grid including:
• a dome bulging in a first direction and having a grid pattern formed thereon;
• an annular flange surrounding the dome;
• a skirt surrounding the annular flange and extending in a direction opposite the first direction, such that when the grid is mounted in the VED between the cathode and anode with the dome in confronting relationship to the cathode, the skirt extends from the flange towards the anode, the dome, the annular flange, and the skirt formed on a deposition surface that includes a skirt template;
• and
• one or more alignment orifices disposed in the annular flange.
