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...

Abstract: In order to estimate in absolute terms the luminosity of LHC certain beam parameters have to be measured very accurately. In particular the total beam current and the relative distribution o...

A new method for generation of quasimonoenergetic and low emittance fast ion/nuclei bunches of solid densities from nanotargets by two counterpropagating laser pulses of ultrarelativistic intensities ...
Design of magnet and control of the beam emittance for Penning H－ ion source
H－ ion source Magnetron ion source Penning ion source magnetic field gradient index
2009/8/14
The design requirement and principle of the deflection magnet for Magnetron and Penning H－ ion source are discussed. It is proved that there exists a maximum emittance for the beam that may be transf...
