DRIVE REQUIREMENTS FOR HIGH-VOLTAGE LOW-GRID-CURRENT TUBES.

Abstract

Modern hard-tube modulator structures using a magnetic field to focus the electron beam have reduced the intercepted grid current by an order of magnitude. This has resulted in significant reduction in the required drive power. In order to achieve the full current capability of these tubes during the pulse rise time, the displacement current required to discharge the tube and circuit capacitance between grid and plate must be supplied by the driver. Typical calculations and curves showing the effect of the driver current on rise time are included. (Author)
