The maintenance required to keep up a dependable 24/7/365 vacuum and water source is difficult. The vacuum level required to operate a field emission gun is greater than a DP can produce. Ion (or ...

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.

By enabling accelerating voltages as low as 0.01 kV, it improves surface topography and enhances resolution at low kV. JEOL's unique in-lens field emission gun integration allows for a beam current of ...

It also enhances resolution at low kV and improves surface topography by enabling accelerating voltages down to 0.01 kV. The integration of JEOL’s specific in-lens field emission gun enables a beam ...

This instrument is an advanced and digitally dedicated transmission electron microscope operating at 200kV with a field-emission gun. It is capable of an ultimate point-to-point resolution of 0.19 nm, ...
