A Gating Grid Driver for Time Projection Chamber

Executive SummaryTime Projection Chambers (TPCs) are uniquely useful in analyzing nuclear reactions and resulting particles. These devices rely on fast gating systems to allow or deny entry of particles into the detection area; without which they would not be functional. MSU researchers have developed a novel gating grid driver system for TPCs. Due...

RF Detection of Analytes

Executive SummaryDue to public health concerns since the 1920’s, the U.S. dairy industry is federally required to be monitored and treated for bacterial contamination. Most municipalities mandate pasteurization to reduce the number of viable pathogens likely to cause disease. Pre- and post-pasteurized milk is often tested for contamination via...

Viscosity-Corrected Shear Speed Estimates and Shear Speed Images

Executive SummaryUltrasound imaging relies on sound waves to develop ultrasound images, which are used in diagnostics for a wide variety of medical conditions affecting organs and soft tissues. Current approaches to estimate shear wave speed for shear wave elastography imaging in viscoelastic soft tissue consistently overestimate the shear speed, due...
