Abstract
A system for determining Schottky thermal field emission (TFE) usable current and brightness of a Schottky TFE source is provided, the system including: one or more processors, configured to: acquire and store in a memory a Schottky TFE emission image in a digital format; and determine Schottky TFE usable beam current and brightness for the based on experimentally developed algorithms that utilize usable current criteria and usable emission current density, the usable current criteria being generated based on properties of a central beam component and an outer beam component of Schottky TFE beam current.
