Abstract:
An emitter assembly for emitting a charged particle beam along an optical axis is described. The emitter assembly being housed in a gun chamber and includes an emitter having an emitter tip, wherein the emitter tip is positioned at a first plane perpendicular to the optical axis and wherein the emitter is configured to be biased to a first potential, an extractor having an opening, wherein the opening is positioned at a second plane perpendicular to the optical axis and wherein the extractor is configured to be biased to a second potential, wherein the second plane has a first distance from the first plane of 2.25 mm and above.

Claim (Index 1):
A charged particle beam device configured for a high energy charged particle beam within the charged particle beam device, wherein the beam energy within the column is at least 10 times higher compared to the landing energy of the charged particles, the charged particle beam device comprising:\n an emitter assembly for emitting an electron beam along an optical axis, the emitter assembly being housed in a gun chamber, the emitter assembly comprising:\n a field emitter having an emitter tip, wherein the emitter tip is positioned at a first plane perpendicular to the optical axis and wherein the field emitter is configured to be biased to a first potential; and \n an extractor having an opening, wherein the opening is positioned at a second plane perpendicular to the optical axis and wherein the extractor is configured to be biased to a second potential, wherein the second plane has a first distance from the first plane of 2.25 mm or above; and \n a control power supply connected to the extractor and connected to ground.
