FIRST MEASUREMENTS OF CLEAR AT THE NATIONAL ACCELERATOR CENTER
During the week of February 6 to 9, and within the framework of the European project EUROpean Laboratories for Accelerator Based Science (EURO-LABS), researchers from the Faculty of Sciences of the University of Lisbon (Dr. Daniel Galaviz Redondo, Francisco Geraldes Barba, Ricardo Matoza Pires and Beatriz María Lopes Amorim), together with members of the local team of the Basic Nuclear Physics Unit of the National Accelerator Center (Dr. Begoña Fernández and Dr. Francisco Javier Ferrer) have carried out elemental characterization measurements of solid targets helium used in the IS698 EXPERIMENT AT THE ISOLDE-CERN facility. In that experiment, high intensity radioactive beams of tin (Sn-108 and Sn-110) were produced, which bombarded solid targets enriched with helium (He-4). The data collected will make it possible to perform an analysis to strengthen the study of nuclear properties and deduce nuclear potentials from reactions with alpha particles to find out how elements rich in protons are generated.
The elemental characterization (before and after the experiments) of the targets used in nuclear reaction experiments is essential for the correct interpretation of the results obtained in said experiments. For several years, this characterization work has been carried out with great success at the CNA thanks to the application of ion beam analysis (IBA) techniques.
The CNA is part of the CLEAR (Cluster of Low Energy Accelerators for Research) consortium, which is a group made up of three facilities (ATOMKI in Debrecen, CNA in Seville and IST in Lisbon) that offer access to stable ion and neutron beams, in the framework of the EURO-LABS project. The experiments carried out at the CNA mean the launch of this experimental work platform with accelerators in Seville.
