The neutral beam deposition model in the BEAMS3D code is validated against neutral beam attenuation data from Wendelstein 7-X (W7-X). A set of experimental discharges where the neutral beam injection system of W7-X was utilized were reconstructed. These discharges scanned the magnetic configurations and plasma densities of W7-X. The equilibrium reconstructions were performed using STELLOPT which calculates three-dimensional self-consistent ideal magnetohydrodynamic equilibria and kinetic profiles. These reconstructions leveraged new capabilities to incorporate electron cyclotron emission and x-ray imaging diagnostics in the STELLOPT code. The reconstructed equilibria and profiles served as inputs for BEAMS3D calculations of neutral beam deposition in W7-X. It is found that if reconstructed kinetic profiles are utilized, good agreement between measured and simulated beam attenuation is found. As deposition models provide initial conditions for fast-ion slowing down calculations, ...

在Wendelstein 7-X上验证BEAMS3D中性束沉积模型

针对来自Wendelstein 7-X（W7-X）的中性束衰减数据验证了BEAMS3D代码中的中性束沉积模型。重建了一组实验放电，其中利用了W7-X的中性束注入系统。这些放电扫描了W7-X的磁性构型和等离子体密度。使用STELLOPT进行平衡重建，该STELLOPT计算三维自洽的理想磁流体动力学平衡和动力学曲线。这些重建利用了新功能，将电子回旋加速器发射和X射线成像诊断程序纳入了STELLOPT代码。重建的平衡和轮廓用作W7-X中BEAMS3D计算中性束沉积的输入。发现如果利用重构的动力学曲线，发现测量和模拟光束衰减之间的良好一致性。由于沉积模型为快速离子减慢计算提供了初始条件，因此...
