Title: Gerhard B. Kuehne: Innovator in Electron Tube Technology

Introduction

Gerhard B. Kuehne is a notable inventor based in Santa Clara, California. He has made significant contributions to the field of electron tube technology, holding three patents to his name. His work has been instrumental in advancing the functionality and efficiency of linear-beam electron tubes.

Latest Patents

One of Kuehne's latest patents is the Zero-bias gridded gun. This innovative device is designed for a linear-beam electron tube and features a control grid that modulates the beam current. The grid consists of an array of conductive web elements, which are spaced much farther apart from each other than from the concave emissive surface of the cathode. This design allows the grid to operate at cathode potential while beam current is drawn, without distorting the electric accelerating field. As a result, the focusing of the beam remains intact. The grid can pulse the beam current on and off with zero bias in the 'on' condition, simplifying the pulse modulator significantly.
