Description

One of the current limitations of predicting the nuclear astrophysics r-process abundance is the lack of data on neutron-rich isotopes; measured neutron-capture cross-sections are the scarcest data. These cross-sections are also invaluable for nuclear reactions and structure in general. The current limitations come from the instability of the target and the projectiles. We proposed a method to overcome this limitation. The goal of this work is the selection and storage of fission fragments in a triple RFQ system. These stored ions will then be hit with an intense neutron beam. The reacted ions will then be ejected and measured using a multiple-reflection time-of-flight mass-spectrometer (MR-TOF-MS).

This poster will mainly focus on the RFQ-3 system that will be installed at Soreq Applied Research Accelerator Facility (SARAF-II)[1], currently under construction in Yavne, Israel. The existing RFQ-3 system [2] will be recommissioned and optimised for this project at Justus-Liebig-University Giessen, Germany. This recommissioning and optimisation will be presented as well as some of the future goals of the project.
