The new instrument, a JEOL JXA-8230 equipped with LaB6 electron gun, was installed in March 2016, and has been fully operational and open to internal and external users since September 2016.

A vacuum provides the needed insulation to prevent "arching" or jumping of high voltages in the electron gun. The gun itself is under extremely high vacuum conditions, requiring a pressure as low as ...

The main platform showcases an electron gun, encased within a glass jar that is further encased within a metal mesh to prevent the glass from spreading too far in the event of an implosion.

An electron gun at the bottom fires high-energy electrons, which are refined by lenses and an aberration corrector for precision. These electrons either pass through or interact with the sample, ...

When the bottom-right corner was reached, the electron gun was returned to the top-left corner, known as the "vertical retrace." For TV signals, these "flyback" periods in which the electron beam ...

The tube has graphite and aluminum foils mounted on a grid between the electron gun and the screen of the tube. The path of the electron beam may be varied so that the beam passes through one of the ...

Featuring an innovative compact FE electron gun made of mild steel with double O-ring sealing, the PE-300 offers fast and accurate gun axis alignment. With superior quality and a competitive price, ...
