Title: The Innovations of Leonard N Litzenberger

Introduction

Leonard N Litzenberger is a notable inventor based in Andover, MA, who has made significant contributions to the field of electron beam technology. With a total of three patents to his name, his work has advanced the understanding and application of electron beam evaporation processes.

Latest Patents

One of his latest patents is the "Linear electron beam gun evaporator having uniform electron emission." This invention focuses on a linear electron beam evaporation source designed for high vapor temperature materials, such as uranium. The source incorporates a filamentary emitter and includes apparatus for controlling the filament electron emission to maintain a consistent current per filament unit length. A control structure is utilized to create a space charge around the electron emitting filament, allowing the current density of the electron beam to be regulated by the space charge rather than the local electron emissivity along the filament's length.

Another significant patent is the "Method and apparatus for measuring vapor flow in isotope separation." This invention features a probe that detects the evaporation rate of an electron beam evaporation source while monitoring the induced ionization of the vapor. A negatively biased electrode is employed to respond to ions in the vapor, measuring the ion current density. The ions detected may arise from the vaporization process or from laser-produced isotopically selective ionization. The probe provides a current output that serves as an indication of the vaporization or laser ionization rate.
