Laser beam incident on the structured droplet sets up plasma waves (blue pulses) that accelerates electrons (green solid spheres) to megaelectronvolt energies. In massive particle accelerators, ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

Researchers have achieved real-time capture of the ionization process and subsequent structural changes in gas-phase molecules through an enhanced mega-electronvolt ultrafast electron diffraction (MeV ...
