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 ...

A team of researchers in Japan has created the world's smallest shooting game, played by manipulating nanoparticles less than ...

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 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.

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.

a JEOL JXA-8230 equipped with LaB6 electron gun (PIs K.H. Mahan, J.M. Allaz, and G.L. Farmer). This new instrument will replace the aging JEOL JXA-8600 installed in 1988, and will offer superior ...

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 ...

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, ...

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, ...
