Latest Patents

Riem's latest patents include the "Liquid Ion Chamber Electrode Apparatus" and "Three Terminal Ion Chambers." The Liquid Ion Chamber Electrode Apparatus provides electrode assemblies for LIC imagers that maximize ion collection and the electric field for the minimum bias voltage. This optimization confines ion collection to small regions, resulting in high neutralization efficiencies and fast sweep-out times. With an electrode separation of approximately 0.1 millimeters, pulse voltages of less than 100 volts can be utilized, leading to improved reliability, longer system life, and lower safety risks. The Three Terminal Ion Chambers patent describes a chamber that includes a first electrode coupled to a bias voltage source, spaced apart from a second electrode coupled to ground. A third terminal is positioned between the first and second electrodes, allowing measurement circuitry to assess the charge indicative of the radiation incident to the chamber.
