Physicists at SLAC National Accelerator Laboratory in the US have shattered the record for most powerful beam of electrons, cramming an ultra-high current of around 100,000 amps into an instant. At ...

According to Wang, short, intermittent bunches of electrons can be easily accelerated to high energy by radiofrequency cavities. These cavities produce electric fields that give intermittent ...

Intense, femtosecond laser pulse focused on a nano structured, ordered ‘pillar’ target, exciting beams of ultrashort electron pulses at MeV energies. Highlights the role of such structured surfaces ...

(Nanowerk News) A new publication from Opto-Electronic Advances ("Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography"), discusses tailoring ...

Brookhaven National Laboratory physicist Erdong Wang in a basement lab at Stony Brook University (SBU) with the high-voltage polarized electron gun that will put the "e" — or electrons — in the future ...

(Nanowerk News) The precise control of electron beams in so-called transmission electron microscopes (TEM) makes it possible to analyze materials or molecules at the atomic level. Combined with short ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

Using data collected by NASA's Juno spacecraft as it flew past Jupiter's highly volcanic moon Io in late 2023 and again in ...
