SORCERER: A novel particle-detection system for transfer-reaction experiments at ROSPHERE — •Tobias Beck1, Cristian Costache2, Razvan Lică2, Nicolae M. Mărginean2, Constantin Mihai2, Radu E.

Transfer-reactions have proven to be suitable for the population of low-abundant or unstable nuclei close to the valley of stability though they usually suffer from excessive background due to fusion-evaporation (FE) reactions. SORCERER [1] is a customizable and cost-efficient particle-detection system for such transfer experiments to be studied with the ROSPHERE detector array [2] at the Bucharest Tandem accelerator. It allows for an efficient suppression of contributions from FE reactions and an improvement of the peak-to-background ratio by about one order of magnitude. The construction, characteristics, and performance in a 94Zr(18O,16O)96Zr experiment are presented and further developments are outlined.
