Abstract
The present invention provides electrode assemblies for LIC imagers that maximize ion collection and the electric field for the minimum bias voltage. To achieve this optimization the ion collection is confined to small regions. Due to this limited ion collection region, high neutralization efficiencies and fast sweep-out times can be obtained. Furthermore, with an electrode separation of approximately 0.1 millimeters, pulse voltages of less than 100 volts can be used. Low voltages result in improved reliability, longer system life, and lower safety risks.
