Title: Innovations by Darrell A. Gleichauf: Contributions to Plasma Cleaning and Supercritical Fluid Monitoring
Introduction
Darrell A. Gleichauf, based in Redondo Beach, California, is a notable inventor recognized for his contributions in the realms of plasma cleaning and supercritical fluid monitoring. With two patents to his name, he has played a significant role in advancing technologies used in various scientific applications.
Latest Patents
Gleichauf's latest patent, titled "Low Energy Plasma Cleaning Method for Cryofilms," addresses the challenge of removing cryofilm and organic contaminants from cryogenically cooled surfaces, such as spacecraft cryo-telescope mirrors. This innovative method utilizes low energy plasma with an average ion energy not exceeding 30 eV, effectively separating contaminants through a strategic process involving multiple plasma phases. Initially, a non-reactive plasma cleans the surface, followed by a reactive plasma that targets residual organic materials, concluding with an inert plasma application to eliminate any remaining reactive compounds.
Another of his significant inventions is the "Supercritical Fluid Contamination Monitor." This system effectively monitors contaminants in a flowing stream of supercritical fluid by extracting a sample stream subjected to reduced pressure. The process converts the supercritical fluid back into gas, allowing a quartz crystal microbalance system to measure the amount of non-gaseous contaminants present. This technology is valuable for overseeing both cleaning and extraction processes utilizing supercritical fluids.
