Scientists have created an ultrashort electron beam with five times more peak current than any other similar beam on Earth. Described in a paper published in Physical Review Letters, this achievement ...

Physicists at SLAC National Accelerator Laboratory have generated the highest-current, highest-peak-power electron beams, achieving 100 kiloamps for one quadrillionth of a second.

Measuring shot noise without external influences is not easy. In a metal, the vibration of the atoms’ lattice can push ...

However, people quickly realized that electric current was in fact made of moving electrons. Since electricity is the lifeblood of everything from computers to phones to microwaves, the electron ...

Much like the traditional scanning electron microscope (SEM), the field emission scanning electron microscope uses electrons to illuminate a sample, instead of visible light as is used in optical ...
