This paper presents numerical optimization of geometries of axially symmetric ion traps for mass analyzers. Four geometries have been taken up for investigation: one is the well known cylindrical ion trap (CIT) and three others are new geometries. Two of these newer geometries have a step in the region of the midplane of the cylindrical ring electrode (SRIT) and the third geometry has a step in its endcap electrodes (SEIT). The optimization has been carried out around different objective functions composed of the desired weights of higher order multipoles. The Nelder-Mead simplex method has been used to optimize trap geometries. The multipoles included in the computations are quadrupole, octopole, dodecapole, hexadecapole, ikosipole and tet...
