Breakthrough in Science: University of Arizona Unveils World’s Fastest Electron Microscope Capable of Capturing Electrons in Just One Attosecond

Jakarta –

To researcher at the University of Arizona has announced development The world’s fastest electron microscope. This microscope can capture times of one attosecond. An attosecond is one millionth trillionth of a second or one millionth of a nanosecond.

Electron microscopes use lasers to produce electron beams. These files are used to visualize research subjects and the shorter the file, the faster and better the resulting image will be.

On this machine, the file is several attoseconds long. This means that it can be used to trap electrons in a freeze frame because the speed of the beam matches the speed of the target electron.

“When you get a newer version of a smartphone, the camera gets better,” senior author Mohammed Hassan, associate professor of physics and optical sciences, said in a statement.

“These transmission electron microscopes are the advanced cameras in the latest versions of smartphones; they allow us to make images of things we couldn’t see before – like electrons. With these microscopes, we hope that the scientific community will understand the quantum physics behind electrons. conduction and electronic movement,” he continued.

Progress in the attosecond problem took a lot of time, requiring decades of research in attosecond physics. This field is still relatively young and has a lot of potential that has yet to be explored.

“This is still in the early stages and it is still very basic research. However, the idea is that we are starting to control (electrons). We can measure the movement of electrons in matter. And it is maybe, just maybe we can control a little bit And this could be important for controlling some chemical processes, maybe also biological processes later on,” said the High professor L’Huillier for the Nobel Prize. IFLS science in a separate interview.

This new electron microscopy technique uses ultrashort light pulses, combined with electron beam pulses. It is this pulse synchronization that makes it possible to observe ultrafast processes at the atomic level.

“Improved temporal resolution in electron microscopes has long been anticipated and is the focus of many research groups, as we all want to see the movement of electrons,” said Hassan.

“This transition occurs in the matter of attoseconds. But now, for the first time, we are able to achieve an attosecond temporal resolution with our transmission electron microscope. We call it ‘attomicroscopy’. ‘ “For the first time, we were able to see electronic bits of electrons,” he admitted.

This research was published in the journal Science Advances.
