Description

The polarized target is an essential part of the experimental program at the Bonn accelerator facility ELSA. In recent years, the polarized target has been successfully used in various experiments to measure single and double polarization observables at the Crystal Barrel Detector at ELSA. Since our experimental program is limited to real photons, we use the classical frozen spin target technique (horizontal dilution refrigerator in combination with internal holding coils). Besides a reliable operation of the target, long relaxation times and high polarization values in proton and deuteron target materials have been achieved in the scattering experiments. I will present the activities of the Bonn Polarized Target Group, the current status and new developments of the group also with respect to the European research funding program CryPTA.
