Exploring Minimal Scenarios to Produce Transversely Bright Electron Beams Using the Eigen-Emittance Concept
emittance free electron laser x-rays emittance exchange eigen-emittance
2011/8/4
Abstract: Next generation hard X-ray free electron lasers require electron beams with low transverse emittance. One proposal to achieve these low emittances is to exploit the eigen-emittance values of...

satellite observations 100 kHz radio waves relativistic electron beams thunderclouds
2011/2/24
Relativistic electron beams above thunderclouds emit 100 kHz radio waves which illuminate the Earth's atmosphere and near-Earth space. This contribution aims to clarify the physical processes which ar...
A new twist on transmission electron microscopy (TEM) could enable the technique to unlock even more secrets on the nanoscale. Researchers in the US have produced a helical-shaped beam of electrons th...
