Source_spectra ComponentThis is a source component for connecting SPECTRA 10-output files with McXtrace. json-style SPECTRA 11 output files are not yet supported. SPECTRA is an application software to calculate optical properties of synchrotron radiation (SR) emitted from bending magnets, wigglers (conventional and elliptical) and undulators (conventional, helical, elliptical and figure-8). Calculations of radiation from an arbitrary magnetic field distribution are also available. Parameters on the electron beam and the source can be edited completely on graphical user interfaces (GUIs) and it is possible to show the calculation result graphically. The energy spectrum and radiation power after transmitting various filters and convolution of detector's resolution are also available. See SPECTRA. If the source is symmetric in x and/or y it is possible to speed up the spectra calculations by only including one half-plane or quadrant. The other side/quadrants will then be mirrored by McXtrace. %BUGS Absolute intensity of 4D (x,y,x',y') is nor correctly normalized.
