Description

In order to extend our research activities towards lighter elements and to diminish the workload on RITU at JYFL, our team has designed a new vacuum separator. The new separator is ideally suited to investigations of nuclei in the A = 50-150 mass region produced in (near) symmetric or inverse reactions. An electromagnetic mass separator was chosen to fulfil these requirements. The design for this new separator will be an energy and angle focussing recoil mass spectrometer. The ion optics code GIOS has been used to design the configuration of magnetic and electric elements. Two bending elements will be used and ordered with an electric dipole (E) followed by a magnetic dipole (M). The EM structure is augmented with a quadrupole triplet (QQQ) lens system to increase the solid angle and to improve the final angular focus. In these simulations a maximum angular acceptance better than 10 msr was achieved and a mass resolving power better than 1/350 (with 5 msr acceptance) was attained.
