研究目的
Investigating the tomographic capabilities of the Minimum Fisher Information (MFI) algorithm for monitoring impurity density and avoiding tungsten accumulation in the tokamak WEST.
研究成果
The MFI method has been successfully adapted for the WEST configuration, showing good reconstruction capabilities for both impurity and main ion emissivity profiles. The method is validated for the standard WEST scenario, indicating its potential for real-time monitoring of impurity densities.
研究不足
The study is based on synthetic data and phantoms, which may not fully capture the complexities of real experimental conditions. The computational time increases with the spatial resolution, limiting real-time applications for high-resolution grids.
1：Experimental Design and Method Selection:
The study uses the Minimum Fisher Information (MFI) method for SXR tomography, adapted from Tore Supra for WEST. The method includes anisotropic smoothing based on the magnetic equilibrium.
2：Sample Selection and Data Sources:
Synthetic SXR measurements derived from emissivity phantoms and a standard WEST scenario are used.
3：List of Experimental Equipment and Materials:
The WEST SXR diagnostic is equipped with two new GEM based poloidal cameras with Beryllium windows.
4：Experimental Procedures and Operational Workflow:
The study involves generating synthetic measurements, applying the MFI method for tomographic reconstruction, and analyzing the results.
5：Data Analysis Methods:
The quality of tomographic reconstruction is assessed using the RMSem metric, and the influence of noise and computational time is analyzed.
