Artificial collimation of fast-electron beams with two laser pulses

A scheme for artificially collimating fast-electron beams produced in high intensity (>1019Wcm-2) laser-solid interactions is proposed. The scheme uses a laser pulse at the relativistic threshold (1018Wcm-2) that precedes the high intensity pulse to pregenerate a collimating magnetic field. T...

Tóm tắt:A scheme for artificially collimating fast-electron beams produced in high intensity (>1019Wcm-2) laser-solid interactions is proposed. The scheme uses a laser pulse at the relativistic threshold (1018Wcm-2) that precedes the high intensity pulse to pregenerate a collimating magnetic field. This concept is supported by analytical calculations and numerical calculations performed using a novel hybrid-Vlasov-Fokker-Planck code called LEDA. This scheme may be highly useful for fast ignition inertial confinement fusion. © 2008 The American Physical Society.
