Fully automated adjustment of the electron beam line of the 2 MeV Electron Cooler at the Cooler Synchrotron @ FZ-Jülich — •Arthur Halama and Vsevolod Kamerdzhiev — Forschungszentrum Jülich, IKP-4

The 2 MeV electron cooler has maximal design parameters, such as 2 MeV electron kinetic energy and 3 A current. Its entire transport line guides the electron beam using a longitudinal magnetic field. Up to now the beam line is setup mostly manually. As this is time consuming and particular beam properties are linearly coupled, the design parameters could not be reached yet. A control software is being developed to adjust the beam line for a cool and low-offset beam transport and a high collector efficiency. The software uses field maps of all given magnets to simulate all known influences onto the electron's trajectory using particle tracing. Thus there is not only a model to describe the trajectory, but also to obtain responses to any number of changes within the system. Linear optimization calculations of the responses will yield the wanted magnetic beam line setting to get closer to the design parameters.
