Tangentially viewing soft x-ray (SXR) cameras are capable of detecting nonaxisymmetric plasma structures in magnetically confined plasmas. They are particularly useful for studying stationary perturbations or phenomenon that occur on a timescale faster than the plasma rotation period. Tangential SXR camera diagnostics are planned for the DIII-D and NSTX tokamaks to elucidate the static edge magnetic structure during the application of 3D perturbations. To support the design of the proposed diagnostics, a synthetic diagnostic model was developed using the CHIANTI database to estimate the SXR emission. The model is shown to be in good agreement with the measurements from an existing tangential SXR camera diagnostic on NSTX.
切向观察软X射线（SXR）相机能够检测磁约束等离子体中的非轴对称等离子体结构。它们对于研究比等离子体旋转周期更快时间尺度上发生的静态扰动或现象特别有用。计划在DIII-D和NSTX托卡马克装置上采用切向SXR相机诊断，以阐明三维扰动应用期间的静态边缘磁结构。为支持所提议诊断的设计，利用CHIANTI数据库开发了一个综合诊断模型来估算SXR发射。该模型与NSTX上现有切向SXR相机诊断的测量结果显示出良好的一致性。
