In this work, we present the measurement of L-band emission from buried Sc/V targets in experiments performed at the OMEGA laser facility. The goal of these experiments was to study non-local thermodynamic equilibrium plasmas and benchmark atomic physics codes. The L-band emission was measured simultaneously by the time resolved DANTE power diagnostic and the recently fielded time integrated Soreq-Transmission Grating Spectrometer (TGS) diagnostic. The TGS measurement was used to support the spectral reconstruction process needed for the unfolding of the DANTE data. The Soreq-TGS diagnostic allows for broadband spectral measurement in the 120 eV-2000 eV spectral band, covering L- and M-shell emission of mid- and high-Z elements, with spectral resolution λ/Δλ = 8-30 and accuracy better than 25%. The Soreq-TGS diagnostic is compatible with ten-inch-manipulator platforms and can be used for a wide variety of high energy density physics, laboratory astrophysics, and inertial confinement fusion experiments.
在这项工作中，我们展示了在欧米茄激光装置上进行的实验中对埋入式钪/钒靶L波段发射的测量。这些实验的目的是研究非局部热力学平衡等离子体并对原子物理代码进行基准测试。L波段发射由时间分辨的DANTE功率诊断仪和最近投入使用的时间积分索雷克传输光栅光谱仪（TGS）诊断仪同时测量。TGS测量用于支持展开DANTE数据所需的光谱重建过程。索雷克-TGS诊断仪能够在120 eV至2000 eV光谱波段进行宽带光谱测量，涵盖中高Z元素的L壳层和M壳层发射，光谱分辨率λ/Δλ = 8 - 30，精度优于25%。索雷克-TGS诊断仪与十英寸机械手平台兼容，可用于各种高能量密度物理、实验室天体物理和惯性约束聚变实验。
