Ion optical simulations for the NEXT solenoid separator — •Arif Soylu1, Xiangcheng Chen1, Julia Even1, Alexander V. Karpov2, Vyacheslav Saiko2, Jan Sáren3, and Juha Uusitalo3 — 1University of Groningen, Groningen, The Netherlands — 2Dubna, Russia — 3University of Jyväskylä, Jyväskylä, Finland
The NEXT project aims to study Neutron-rich, EXotic heavy nuclei produced in multi-nucleon Transfer reactions[1]. In order to focus and separate these transfer products from unwanted by-products and unreacted primary beam, a 3T solenoid magnet with an 87-cm wide bore will be used.
A Python code was developed to simulate the trajectories of ions through the magnetic field of the solenoid magnet. The purpose of this simulation is to determine the optimal settings for the solenoid separator in order to achieve the highest transmission yields for the ions of interest and the strongest background suppression.
In my contribution, I will explain the various stages involved in the simulations of the ion trajectories through the magnetic field. I will present the simulation results obtained for selected multinucleon transfer products that are of interest for nuclear structure and nuclear astrophysics.
