摘要

An experimental measurement of radiatively heated iron plasma transmission spectra was performed on Shenguang Ⅱ laser facility.In the measurement,the self-emission spectrum,the backlighting spectrum,and the absorption spectrum were imaged with a fiat filed grating and recorded on a gated micro channel plate detector to obtain the time-resolved transmission spectra in the range 10-20 A (approximately 0.6-1.3 keV).Experimental results are compared with the calculation results of an unsolved transition array (UTA) code.The time-dependent relative shift in the positions of the 2p-3d transmission array is interpreted in terms of the plasma temperature variations.
