In this work we study the imaging properties of the KATRIN solenoid chain from the center of the WGTS source to the symmetry point of the main spectrometer entrance solenoid by calculating the trajectories of 200 representative electrons numerically with the simulation package PartOpt. By using both the microscopic approach and the drift equations during the calculation, depending on the magnetic field strength, the calculation times could be reduced to several minutes per trajectory. The image of a cross-type start pattern is produced and it is shown that the maximal energy loss due to synchrotron radiation is less then 0.11eV.
