Scientists have created an ultrashort electron beam with five times more ... In astrophysics, for example, this beam can be ...

The most powerful ultrashort electron beam ever created offers new possibilities for recreating cosmic conditions in ...

In scanning electron microscopy, a thermionic electron source such as a tungsten filament is usually used ... Because of the microscopic size of the electron source, the beam produced by this emitter ...

For example, in astrophysics, the high-powered electron beam can be directed at solid or gas targets to simulate the filaments found in stars. Scientists have long observed these filaments in ...

A plasma instability has been photographed for the first time, showcasing electron beams forming spaghetti-like filaments.

Special features: The electron beam is produced by a LaB 6 filament giving excellent signal-to-noise and good contrast. It provides long term, stable operation with approximately ten times the ...

Unlike the electron ... the beam in a focused ion beam system (FIB) is composed of gallium (Ga) ions. The ions forming the structure of the beam are derived from a liquid metal ion source (LMIS). In ...

Molybdenum diselenide nanodots, represented by red triangles, are embedded in tungsten diselenide and encapsulated by hexagonal boron nitride (hBN) on top and bottom. A focused electron beam ...
