Normalized fifth-order spherical aberration coefficients derived from a Gaussian trajectory on rotationally symmetrical magnetic lenses.
This paper reports normalized fifth-order spherical aberration coefficients C(5s)/R derived from Gaussian trajectory for rotationally symmetrical magnetic lenses, where S/D (the polepiece gap-width/bore-diameter ratio) is in the range 0.20-2.00, and k(2) (the lens-intensity parameter) is 0.10-100. It is noted that the normalized fifth-order spherical-aberration coefficient C(5s)/R changes its sign within the given parameter ranges.
