Soft x-ray tomograms are inferred from experimental data obtained during the recent operational phases of the superconducting, optimized stellarator Wendelstein 7-X. It is shown that the reconstructed soft x-ray emission profiles of the plasma are consistent with the numerically calculated magneto-hydrodynamic equilibrium of Wendelstein 7-X. In order to obtain reliable tomograms, the full chain of electrical and geometrical influences on the x-ray observation has to be taken into account. This has been achieved by formulation and application of an extended forward model. The forward model has been verified using phantom data derived from surrogate tomograms.

软 X 射线断层图像是从超导优化仿星器 Wendelstein 7-X 最近运行阶段获得的实验数据推断出来的。结果表明，重建的等离子体软 X 射线发射剖面与文德尔斯坦 7-X 的数值计算磁流体动力学平衡一致。为了获得可靠的断层图像，必须考虑对 X 射线观察的电气和几何影响的完整链。这是通过扩展前向模型的制定和应用来实现的。前向模型已使用从替代断层扫描图像导出的幻影数据进行了验证。
