* [email protected] Abstract The generation of an ultrashort relativistic electron bunch from a strong laser-plasma interaction have been studied by particle-in-cell simulations and observed experimentally. The electron beam was generated from the plasma created by focusing a Ti: sapphire 50fs 12 TW laser pulse at the edge of helium gas jet expanded into the vacuum from a pulsed supers...

Atomic-field bremsstrahlung has been studied with a longitudinally polarized electron beam. The correlation between the initial orientation of the electron spin and the angle of photon polarization has been measured at the photon high energy tip region. In the time reversal this corresponds to a so-far unobserved phenomenon of production of longitudinally polarized electrons by photoionization ...

In electron beam ion sources, step-wise ionization to high charge states is accomplished by magnetically confined electron beam. Electron space charge and high voltage electrodes confine the ions. The relativistic heavy ion collider (RHIC) ion source Debye length meets requirements for instabilities with free source of energy to grow. Electrons stripped from ions provide energy for a variety of...
