Title: Richard D. Blaugher: Innovator in Superconducting Technologies

Introduction

Richard D. Blaugher is a notable inventor based in Pittsburgh, PA (US), recognized for his contributions to superconducting technologies. He holds a total of 3 patents, showcasing his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is a selective silicon dioxide etchant for superconductor integrated circuits. This invention presents an improved method for providing silicon dioxide with openings that expose contact pad areas for connections to superconductors. The method involves depositing a silicon dioxide film on a substrate, placing a resist film on it, patterning the resist film, and reactive ion etching the exposed portions. The improvement utilizes an etchant gas consisting of 50-95 volume percent nitrogen trifluoride and 5-50 volume percent rare gas, effectively avoiding carbon-containing etchants and polymer by-products.

Another significant patent is the low modulus damping film, which accommodates high shear strain in a rigidly supported epoxy impregnated Nb₃Sn superconducting coil. This invention is crucial in generator applications where the superconducting coil is subjected to various forces. The low modulus material at the interface reduces or distributes shear strain, preventing degradation in current-carrying properties. Suitable materials for this application include polyethylene terephthalate Mylar and polycarbonate Makrofol KG, with adhesives like polyurethane Bostik 7070 used for affixing the film.
