Cbjlf

1. Code Name: Cbjlf (Tokamak calibration code).
2. The scope: Response functions for magnetic diagnostics
3. Developer: Leonid E. Zakharov.
4. Users: LEZ.
5. Description: Reconstruction of response functions from calibration shots.
6. Language: C/OpenGL/CodeBuilder (Cb).
7. CodeControl: Real time interactive, organized by Cb.
8. Communications:Distributed over sections and organized by Cb (I/O file system, X-Window and OpenGL graphics with .png, .eps output). Linked to MDSplus system of NSTX, LTX, JET, C-mod, DIII-D, MAST, EAST.
9. Postprocessors: Other Cb-codes can read files from I/O database (the structure of records is common). Standard software for movie files.
10. Docs: Online-Help and code maintenance documentation is organized by Cb.
11. Web: N/A
12. Versions: No version control.
13. NumModel: Integral equation for response functions as the time dependent core related the waveforms of magnetic signals and the coil currents.
14. OperModel Linear algebra, regularization of signals.
15. Reference: N/A.
16. Uniqueness: (a) No analogs; (b) Direct way of taking into account the effect of eddy currents on readings of magnetic signals.
17. Verification: Backward reproduction of experimental signals. The accuracy of the code exceeds the uncertainties in diagnostics.
18. Tangible results: (a) Revelation of inconsistencies in magnetic diagnostics of CDX-U; (b) Calibration of magnetic diagnostics of CDX-U, LTX; (c) Reconstruction of CDX-U discharges in the presence of high level of 3-D eddy currents.
19. Limitations: Not visible.
20. Externals: CodeBuilder.
21. Scalability: Not an issue.
22. Bottlenecks: Not visible.
23. Composition: The code is structured by communication sections (rather than by modules or smaller codes) in consistency with Cb.
24. Portability: Not an issue.
25. Performance: Characteristic time is about 1-5 sec/response function.
