Abstract :
Pulsed Airborne and Millimeter Wave TWTs often need very small gridded guns which are difficult to fabricate. Enter the "Negative Grid", which consists of a single grid at a potential near or below that of the cathode. This operating voltage makes the grid non-intercepting and allows close spacing to the cathode surface. This paper will include both simulation data and measured product performance data.
