Identification of tungsten spectra in X-ray range on EAST Tokamak using Flexible Atomic Code
Abstract New tungsten X-ray spectral lines were observed using the X-ray Crystal Spectrometer (XCS) system on the Experimental Advanced Superconducting Tokamak (EAST), with wavelengths ranging from 3.90 Å to 3.98 Å. Preliminary analysis suggests that these previously unidentified lines are emitted by W 43+ , W 44+ and W 45+ . To further validate these observations, this study utilizes the Flexible Atomic Code (FAC) and FLYCHK codes to calculate the emission spectra and ion charge-state distributions, respectively. Strong agreement between theoretical calculations and experimental observations confirms the accuracy of the spectral identification.
