The JEOL TEM-F200 is a 200kV S/TEM equipped with a Cold Field Emission Gun for high brightness and a narrow energy spread, supporting high energy resolution electron energy loss spectroscopy (EELS).

Although similar guns existed at SLAC ... measures transverse position changes in the beam as a function of electron energy. Ideally, if the trajectory is straight down the centre of the magnets ...

A beam of electrons is produced at the top of the microscope by an electron gun. The electron beam follows a vertical path through the microscope, which is held within a vacuum. The beam travels ...

Tecnai ST20 is a 200 kV TEM with a LaB 6 electron gun. The microscope may also be used at lower accelerating voltages, down to 80 kV. It is equipped with an EDS system and software for performing ...
