Dataset for Long-Wavelength Synchrotron Radiation Spectral Calculations and Three-Dimensional Geometric Corrections

Taking electron trajectories in arbitrary magnetic fields as input, the code calculates the single-electron frequency-domain complex field based on retarded potentials and the Liénard–Wiechert field. On a unified single-electron physical baseline, it implements several multi-electron models, including incoherent statistical averaging, explicit coherent field summation, one-dimensional form-factor correction, and three-dimensional geometric form-factor correction.

The program can output two-dimensional photon flux density distributions, central profiles, peak enhancement factors, and total-flux enhancement factors. It also supports parameter scans over wavelength, bunch length, electron number, and macro-particle number, enabling comparison of the applicability and error sources of different coherent-radiation modeling approaches.This update supplements the program code with curated magnetic-field inputs, model-comparison results, wavelength and bunch-length scans, electron-number scans, comparison results from SRW (Synchrotron Radiation Workshop), and original figures and plotting scripts.
