Parasitic Optimization of the Transfer Beamline Efficiency at ELSA — •Sebastian Witt, Klaus Desch, Daniel Elsner, and Dennis Proft — Elektronen-Stretcher-Anlage ELSA, Physikalisches Institut, Universität Bonn

The 3.2 GeV electron accelerator ELSA consists of three acceleration stages each interconnected by tunable transfer beamlines. The steering of the electron beam through the transfer line from linear accelerator to the booster synchrotron is currently adjusted by hand, which limits a systematic optimization of the transfer efficiency.

To improve the situation, an automated optimization using the "simulated annealing" technique has been developed and integrated into the accelerator's control system. It allows for a continuous optimization without interfering with usual beamtime for experiments by utilizing the 6s off-time in between injections into the storage ring. In a simulation using the actual accelerator's settings as starting parameters, transmission rates have been increased significantly, while testing with the accelerator is still ongoing.
