A Compton Backscattering Polarimeter for Electron Beams below 1 GeV

A Compton Backscattering Polarimeter for Measuring Longitudinal Electron Polarization

Compton backscattering polarimetry provides a fast measurement of the polarization of an electron beam in a storage ring. Since the method is non-destructive, the polarization of the electrons can be monitored during internal target experiments. At NIKHEF a Compton polarimeter has been constructed to measure the polarization of the longitudinally polarized electrons stored in the AmPS ring. Fir...

Stimulated Backscattering From Relativistic Unmagnetized Electron Beams

Demonstration of self-truncated ionization injection for GeV electron beams

Ionization-induced injection mechanism was introduced in 2010 to reduce the laser intensity threshold for controllable electron trapping in laser wakefield accelerators (LWFA). However, usually it generates electron beams with continuous energy spectra. Subsequently, a dual-stage target separating the injection and acceleration processes was regarded as essential to achieve narrow energy-spread...
