Understanding chorus waves is vital, as they create fast-moving, highly energetic electrons (known as killer electrons) that ...

FLASH radiation therapy could one day cure complex tumors and cancers while limiting the toll of radiation on the body. France's Institut Curie hopes to install one of the special machines in its ...

In scanning electron microscopy, a thermionic electron source such as a tungsten filament is usually used. The subject of this tutorial, the Hitachi S-4700 FE-SEM, utilizes a cold cathode field ...

Achieving practical interstellar travel requires overcoming the immense challenge of reaching extraordinary velocities. To ...

Common detectors pick up back-scattered electrons bouncing back toward the electron source. There are also low-energy electrons bouncing off in random directions, depending on the topology of the ...

I used to have access to some pretty nice Scanning Electron Microscopes (a SEM) at my day job. While they are a bit more complex than a 3D printer, they are awfully handy when you need them.

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in ...
