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.
