Just as we use lenses to focus and reshape visible light, magnets are used to focus and reshape electron beams.

Rather than the light used in a traditional microscope, this technique uses focused beams of electrons to illuminate a sample and form images with atomic resolution.

The researchers therefore carefully fused the nano - beads by focusing a high - energy electron beam on them, thus forming a continuous crystalline network.

The ultimate dream is to take STEM into three dimensions with confocal electron microscopy, which images a material in slices by changing the focus of the beam.

To identify the location of each element with atomic precision, the researchers used a method in which the electron beam of one of the world's leading ultrahigh - resolution electron microscopes is finely focused, sent through the specimen and, by interactions with the specimen, loses part of its energy.

The team envisions integration across scales by integrating images from different sources, such as light microscopes, focused ion beam scanning electron microscopes (FIBSEM), and TEM.

The research team then focused a beam of vacuum ultraviolet light from the synchrotron on the heated gas mixture that knocked away electrons (an effect known as ionization).

The microscope scans a sample with a focused beam of electrons, and then measures how the electrons interact with the atoms in the sample.

«What is really interesting to me is that you can potentially focus the beam down to a small size, and then you would really have a system that competes with X-ray free - electron lasers,» Minor said, which opens up the possibility of electron imaging of single biological particles.

Filippetto has a goal to improve the focus of the HiRES electron beam from microns, or millionths of a meter in diameter, to the nanometer scale (billionths of a meter), and to also improve the timing from hundredths of femtoseconds to tens of femtoseconds to boost the quality of the images it produces and also to study even faster processes at the atomic scale.

This disk (0.02 of an inch in diameter) is a slice of one of the thousands of electrodes that ruptured when a self - focused, relativistic electron beam pinched into a 630,000,000 °F «hot dot» that was only 4 billionths of an inch in diameter.
