An application program to calculate various characteristics of synchrotron radiation, called SPECTRA , is described. The program does not need any other commercial software and is equipped with a full graphical user interface which makes data input quite easy. Equations on synchrotron radiation from arbitrary‐field sources in a near‐field region are derived, as are simplified expressions for ideal devices using a far‐field approximation. Effective numerical methods implemented in SPECTRA to reduce computation time are explained, and several examples are presented.
