Effect of laser intensity on fast-electron-beam divergence in solid-density plasmas

Abstract:

Metal foil targets were irradiated with 1μm wavelength (λ) laser pulses of 5 ps duration and focused intensities (I) of up to 4×1019Wcm-2, giving values of both Iλ2 and pulse duration comparable to those required for fast ignition inertial fusion. The divergence of the electrons accelerated into the target was determined from spatially resolved measurements of x-ray Kα emission and from transverse probing of the plasma formed on the back of the foils. Comparison of the divergence with other p...
