The field emission SEM (FE-SEM) is capable of reaching a magnification ... A vacuum provides the needed insulation to prevent "arching" or jumping of high voltages in the electron gun. The gun itself ...

Vacuum sealed chamber that contains the field emission gun. A pneumatic valve seals the gun chamber in the event of an accidental vacuum vent. This prevents dust and debris from reaching the tip.
