Title: Herbert W. Friedman: Innovator in Electron Beam Technology

Introduction

Herbert W. Friedman is a notable inventor based in Marblehead, MA (US). He has made significant contributions to the field of electron beam technology, particularly through his innovative patent.

Latest Patents

Friedman holds a patent for an "Electron beam heated thermionic cathode." This invention involves a fully impregnated dispenser cathode member that forms part of an electron tube or electron beam generator. The cathode is initially heated to a temperature sufficient for low-level electron emission from its rear surface. A hot plate member, preferably equal in size, is positioned behind the cathode. This hot plate can either be part of the initial heating means or heated alongside the cathode to achieve the desired emission temperature. A sustainer voltage is applied between the cathode and the hot plate, facilitating electron flow and heating the hot plate to maintain the cathode's emission temperature.
