Old Mystery Solved: a "New Kind of Electrons"

Why do certain materials emit electrons with a very specific energy?

20-Nov-2020

It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called "photoelectrons". In materials research, so-called "Auger electrons" also play ...

Further understanding of a process that causes heat loss in fusion devices

11-Apr-2017

Everyone knows that the game of billiards involves balls careening off the sides of a pool table — but few people may know that the same principle applies to fusion reactions. How charged particles like electrons and atomic nuclei that make up plasma interact with the walls of doughnut-shaped ...

Radiation that knocks electrons out and down, one after another

12-Dec-2016

Researchers at Japan's Tohoku University are investigating novel ways by which electrons are knocked out of matter. Their research could have implications for radiation therapy. Exposing a small cluster of neon atoms to a very short and intense burst of extreme ultraviolet light initiates a novel ...

Controlling electrons in time and space

16-Nov-2016

In an electron microscope, electrons are emitted by pointy metal tips, that way the can be steered and controlled with high precision. Recently, such metal tips have also been used as high precision electron sources for generating x-rays. A team of researchers at TU Wien (Vienna), together with ...
