In-flight production and separation of positron emitters for hadron therapy — •Emma Haettner for the BARB- and Super-FRS Experiment collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH

The European project on Biomedical Applications of Radioactive Beams, BARB, was launched at GSI in 2021. It aims at pre-clinical validation of in-vivo beam visualization and ion-beam therapy with positron-emitting isotopes of carbon and oxygen. The positron emitters were produced, separated and identified with the Fragment separator FRS at GSI in a joint experimental effort of the the FRS and the biophysics groups at the GSI and Department of physics at LMU. In the first experiments different hadron therapy relevant positron emitters were investigated in terms of intensity, purity, energy, and energy spread. One branch of the FRS is connected to the bio-medical cave of the GSI. Here, we present the new ion-optical mode and commissioning results of the FRS-Cave M branch where positron emitting 15O-ions were provided to the medical cave for first time and also imaging results from experiments at the main branch of the FRS.

This work is supported by ERC Advanced Grant 883425 (BARB) to M. Durante. The measurements were performed within the Super-FRS Experiment Collaboration (Exp. No. S533 by S. Purushothaman et al.) in the framework of the FAIR Phase-0 experimental program.
