Abstract
Time resolved hard x-ray images (hv > 9 keV) and time
integrated hard x-ray spectra (hv = 18-150 keV) from vacuum hohlraums
irradiated with four 351 nm wavelength NIF laser beams are presented as a
function of hohlraum size and laser power and duration. The hard x-ray
images and spectra provide insight into the time evolution of the hohlraum
plasma filling and the production of hot electrons. The fraction of laser
energy detected as hot electrons (f
shows correlation with both
laser intensity and with an analytic plasma filling model.
