Title: Keith T Gillen: Innovator in Surface Diagnostics

Introduction

Keith T Gillen is a notable inventor based in Palo Alto, California. He has made significant contributions to the field of surface diagnostics through his innovative patent. His work focuses on the analysis of unknown species of matter present on surfaces, even in extremely low concentrations.

Latest Patents

Gillen holds a patent for a "Method and apparatus for surface diagnostics." This invention involves a method and apparatus for mass spectral analysis of unknown species of matter present on a surface. A probe beam, such as an ion beam, electron beam, or laser, is directed to the surface under examination to remove a sample of material. An untuned, high-intensity laser is then directed to a spatial region near the surface. The laser has sufficient intensity to induce a high degree of nonresonant, and hence non-selective, photoionization of the sample of material within the laser beam. The non-selectively ionized sample is subsequently subjected to mass spectral analysis to determine the nature of the unknown species.
