The Negative Grid gun

2002 / IEEE / 0-7803-7256-5

Description

This item was taken from the IEEE Conference ' The Negative Grid gun ' 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.
