Electron Column

Assembly

A heated or field-emission source emits electrons that an accelerating anode pulls into a beam; condenser and objective electromagnetic lenses demagnify it to a fine probe, apertures trim its tails, and scan coils sweep it across the sample. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
