From the source via accelerators, bunch compressors, collimation system to and through undulators, self effects play an important role for the design and operation of such machines. Unfortunately it is not possible to solve the coupled problem of Maxwell's equations and equations of motion for bunches of 10⁻⁶ to 10⁻³ meter length in machines with a dimension of 100 to 1000 meters. Therefore simplifying concepts as space charge fields, space charge optics, wakes and coherent synchrotron radiation are widely in use. There are even models for parasitic micro-bunch instabilities for wavelengths clearly below one micrometer. Although the individual models are well developed and efficient, it is still difficult to combine them in single program that simulates a machine from the source to the end.
