Estimation of plasma parameters of X-pinch with time-resolved x-ray spectroscopy

Abstract: We estimate the parameters of a Cu plasma generated by an X-pinch by comparing experimentally measured x-rays with synthetic data. A filtered absolute extreme ultraviolet diode array is used to measure time-resolved x-ray spectra with a spectral resolution of ∼1 keV in the energy range of 1–10 keV. The synthetic spectra of Cu plasmas with different electron temperatures, electron densities, and fast electron fractions are calculated using the FLYCHK code. For quantitative comparison with the measured spectrum,… Show more

“…𝜔 𝑘 where, 𝜒 𝑒 is the electron susceptibilities, 𝜀 is the longitudinal dielectric function, and 𝑓 𝑒0 , 𝑓 𝑖0 are velocity distributions of each charge species, respectively. Also, Maxwell-Boltzmann distribution has been assumed for the plasma temperature [9,10]. When calculating expected signals with certain values within estimated variable range of the device, expected signals move in a narrow wavelength range as the plasma jet parameters change, as shown in figure 4.…”
