【 摘 要 】

The paper describes a novel application of an electron beam ion trap as a plasma target facility for intense laser-plasma interaction studies. The low density plasma target (similar to 10(13)/cm(3)) is confined in a mobile cryogenic electromagnetic charged particle trap, with the magnetic confinement field of 1-3 T maintained by a superconducting magnet. Ion plasmas for a large variety of ion species and charge states are produced and maintained within the magnetic field and the space-charge of an energetic electron beam in the electron beam ion trap (EBIT) geometry. Intense laser beams (optical lasers, X-ray lasers and upcoming X-ray free electron lasers (XFEL)) provide strong time varying electromagnetic fields (> 10(12) V/cm in femto- to nano-second pulses) for interactions with electromagnetically confined neutral/non-neutral plasmas. Experimental scenarios with intense photon fields on ionization/excitation processes, the ionization balance, as well as photon polarization effects and tests with intense lasers that utilize the ion plasma target are outlined. A first test of the plasma target with the PHELIX high intensity laser at GSI is described. (c) 2007 Elsevier B.V. All rights reserved.
