摘要：
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 & Aring; to 3.98 & Aring;. Preliminary analysis suggests that these previously unidentified lines are emitted by W43+, W44+ and W45+. 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.
