Werner Stocker

Title: Werner Stocker: Innovator in Electron and Ion Beam Technology

Introduction

Werner Stocker is a notable inventor based in Wadenswil, Switzerland. He has made significant contributions to the field of electron and ion beam technology, holding a total of 2 patents. His work focuses on developing advanced methods for creating and manipulating charged particle beams.

Latest Patents

Stocker's latest patents include a "Low-voltage source for narrow electron/ion beams." This innovative source comprises a sharply pointed tip and an aperture in a thin sheet of material. When the tip is made sharp enough, the electric field between the tip and the aperture causes a stream of electrons to be emitted, forming a beam of free electrons. The design allows for operation in ultra-high vacuum or noble-gas atmospheres, producing either free electrons or noble-gas ions. Another significant patent is the "Method of making self-aligned apertures," which involves fabricating precisely aligned apertures for use in electron and ion microscopy. This method utilizes a sharply pointed tip in front of thin metal foils, where elevated voltage initiates a sputtering operation to create aligned apertures.
