Simulation of Off-Axis Planar Undulator Radiation by Numerical Approach Using SCILAB-Xcos Model

The SCILAB-Xcos model for off-axis planar undulator radiation (UR) has been designed. The model calculates the intensity of off-axis radiation based on a numerical approach. The intensity computation results obtained from the SCILAB-Xcos simulation model are compared with analytical results at different harmonics. The results for on-axis radiation were also compared with free software SPECTRA, a synchrotron radiation (SR) calculation code.
