Title: Robert H. Krech and High-Flux Energetic Atom Technology.

Introduction

Robert H. Krech is an inventor associated with Saugus, Massachusetts, and Physical Sciences, Inc. His work includes a patented method for generating energetic atomic beams and using them to modify material surfaces.

Latest Patents

Krech is credited with 1 patent, titled “Source of High Flux Energetic Atoms.” The invention describes a method and apparatus for producing a nearly mono-energetic beam of atoms traveling at several kilometers per second, with energies of approximately 1–10 electron volts.

The process forces a gas or gas mixture through a nozzle into an evacuated expansion chamber, accelerating the gas in a confined flow. Laser radiation then causes the gas to break down and dissociate into an atomic plasma. As the plasma expands through the nozzle, it reaches the desired velocity. A vacuum chamber helps preserve the gas components and limit collisions.

The resulting beam can alter a target’s surface through erosion, cleaning, coating, or reactions between beam atoms and surface materials. Pulsed operation can support controlled thin-film deposition, potentially down to a single-atom layer.

Career Highlights

Krech’s patent addresses both the generation of high-velocity atomic beams and their practical use in surface processing. The described approach brings together gas-flow acceleration, laser-induced plasma formation, and vacuum-based beam delivery for applications involving material modification.
