Title: J Howard Marshall III: Innovator in Neutron-Capture Analysis

Introduction

J Howard Marshall III is a notable inventor based in Pasadena, CA, with a significant contribution to the field of analytical measurement. He holds 8 patents that focus on improving the accuracy and efficiency of elemental analysis in bulk substances.

Latest Patents

One of his latest patents involves obtaining uniformity of response in analytical measurement. This invention enhances an apparatus for neutron-capture-based on-line elemental analysis by improving the uniformity of response, making it less sensitive to segregations in moving streams of bulk substances. The design incorporates a measurement volume with a substantially square cross-section and rounded corners, which helps exclude the bulk substance from regions of unusual sensitivities. Additionally, the apparatus features multiple neutron sources that expose the analyzed substance to a flux of neutrons, improving measurement uniformity.

Another significant patent by Marshall focuses on controlling neutrons escaping from an elemental analyzer. This invention aims to improve accuracy and reduce potential radiation hazards by strategically placing neutron absorbers around the analyzed substance and neutron source. The careful design ensures that the materials used do not interfere with the detected background events, leading to improved measurement accuracy.
