The soft X-rays mainly originate from the free, hot electrons in the plasma. Therefore, the spectrum of the emission approximately follows a Maxwell-Boltzmann distribution, which corresponds to the temperature of the hot electrons. For the current work, the spectra of the soft X-ray emission were measured for intensities between about 1013 W/cm2 and 1015 W/cm2. The corresponding temperatures of the hot electrons were determined by fitting Maxwell-Boltzmann distributions to the spectra. Furthermore, the resulting H(0.07) dose rates at a distance of 20 cm from the plasma were measured and extrapolated to dose rates for an average laser power of 1 kW.
